[volatilerink]

subj when trying to connect. have installed goodaccess before that and removed it. outline doesn't work at all after goodaccess

[volatilerink]

tried to reinstall outline (after goodaccess). got: "sorry, we could not configure your system to connect to outline. please try running the installer again. if you still cannot install outline, please get in touch with us and let us know that the tap device failed to install with error code 5. [ok]

[temporary-tests]

I have exactly the same problem on Windows 11 Pro (22H2 OS Build 22621.2428) except for I have never used or installed goodaccess. Outline client version 1.11.0 (468189)

[unps]

I have the same problem.

[SergeyAnuchin]

same error on Windows 11 Pro 22H2 22621.2428
update!
Found in eventlog
request failed: could not create route to proxy: command exited with 1 (stdout: Invalid prefix parameter (<>/32). Prefix should be of the form /[0-32]., stderr: ).
Changed in manager server fqdn to ip, created new client connection string and it works!

[temporary-tests]

I accidentally fixed it but I can't say what exactly helped. In my case "outline-tap0" was missing (I forgot that the installer was complaining about it). And like a dozen of "TAP-Windows Provider V9" created by previous installation attempts were in the device manager.
I found that "outline-tap0" can be created using the "C:\Program Files (x86)\Outline\add_tap_device.bat" script, however, when I ran it, the script was failing saying that path was not found. I deleted all copies of "TAP-Windows Provider V9" from the device manger. And then I took commands from the "add_tap_device.bat" script and executed them manually. And they worked, all paths were valid. Outline client started working. I reinstalled the client one more time and it was smooth and everything works now.

[transcendreamer]

Same problem I've got today!
First: 'outline-ipc-start-proxying': error: unknown nativeerror error
Then: Unexpected error. Quitting and restarting may help.
All servers - the same.
And then internet connecting breaks until full PC restart!
Reinstalling doesn't help.
Deleting network adapter and reinstalling doesn't help either.
It's so sad.

[transcendreamer]

Additionally: it's definitely related to the latest Outline update.
I checked reinstalling previous version (1.10.0) and connection works.
Then Outline updates itself and after restarting it stops working!

---

Edit: So the workaround now is staying on version 1.10 and not letting Outline app to update.
Hopefully waiting for fix.

[Talendar]

It seems to be a bug introduced in the latest version (v1.12.0) of the Outline Client.

Jigsaw-Code/outline-apps#1760

[ogreogles]

This may help:
https://support.getoutline.org/s/article/Error-Messages?language=en_US
The steps may vary based on your Windows operating system version, but we’ve provided general steps for how to uninstall the TAP adapter and Outline and then reinstall Outline.
Uninstall the TAP adapter for Outline.
Go to “Device Managers”, then look under “Network Adapters”
Find the “TAP-Windows Adapter V9” file or the TAP adapter associated with Outline
Uninstall or delete this adapter. Keep in mind that this could affect other VPN apps that you have installed.
Uninstall Outline
Go into “Programs & Features”, then go to “Uninstall Program”
Find the Outline app and uninstall Outline
Download the latest version of Outline from getoutline.org and re-install it on your Windows device. The new installation should install a new TAP adapter for you.

As for me, I haven't uninstalled the TAP adapter. I have just updated it. Then I uninstalled the Outline Client and installed the latest version. It works.

[manuelernestog]

I'have the same problem in Ubuntu 22.04 after the last update.

s there any way to prevent it from updating automatically? ?

[maddyhof]

Apologies for the issue. This was reported in Jigsaw-Code/outline-apps#1760 and a new release was pushed today that should resolve it. Closing this as a duplicate.

[SimonZhuangXH]

Still getting the error :(

I shld have the newest client

[Elsayed91]

Same thing

[rustam-python]

I have same error with 1.12.1 (471860) and Windows 11.

[DmitriyYukhanov]

Confirm this is still happening in the latest 1.12.1 (471860) release.

Steps to resolve the problem which worked for me:

1. Uninstall the TAP-Windows Adapter V9 from Device Managers\Network Adapters
2. Uninstall Outline
3. Install the latest Outline version from the official website (installs 1.12.1).

[gggrafff]

I have the same error in Linux. It used to work, I didn't understand at what point it broke. Latest outline client, Linux Mint.

[alexsmik]

Same error. Did all how instruction above, but not working.

[Simplici]

same error with 1.12.1

[alezhu]

Just run c:\Program Files (x86)\Outline\add_tap_device.bat as Administrator

[OskarEichler]

Having the same issue on Windows 10. After it auto-updated to latest version 1.12.1 can't connect to any server and always getting the error 'outline-ipc-start-proxying' error. In previous version it was working but it updated so now it's broken. Running app_tap_device.bat as administrator doesn't fix it. Please check up on this urgently!

[PrevikYT]

same error 1.12.1, add_tap_device.bat doesn't helped

[AlexBonDesigner]

Good afternoon, everyone. Tried everything that was advised and nothing helped. I even reinstalled Windows and nothing helped.

[mRAndron]

I had a similar problem with OpenVPN installed. I removed the TAP-Windows V9 adapter for OpenVPN. After uninstalling everything worked.

Outline client 1.12.1
Win 11 23H2

[DmitriyYukhanov]

Ah, that could be a case for me as well, as I recently installed OpenVPN to access NAS remotely.
But what if you need both OpenVPN and Outline?..

[mRAndron]

Now I tried installing OpenVPN after installing Outline. Outline is still working.

[alekvol]

I haven't run the client on Windows for a long time. I deleted the Outline client and reinstalled it, everything worked. The mobile version of the app was working with an error.

[freesou0]

It worked for me https://superuser.com/questions/1152280/get-net-powershell-cmdlets-failing-with-invalid-class

[DmitriyYukhanov]

I had a similar problem with OpenVPN installed. I removed the TAP-Windows V9 adapter for OpenVPN. After uninstalling everything worked.

Can confirm, it does conflict with OpenVPN.

1. Removed OpenVPN and Outline started working.
2. Installed OpenVPN and Outline can't connect again =(

[Pattriarch]

I also encountered this error in the same version. To resolve the issue, I followed these steps:

1. Uninstall all TAP-Windows Adapter V9 (I also had remnants from IVPN).
2. Uninstall Outline and all other VPNs from the computer, as well as from the browser itself (since conflicts can arise even with an active and functioning VPN due to other extensions).
3. Reinstall Outline, and everything started working again.

[kuzmix]

I've got problem like that at Windows 11

My solution - you should restart service 'outlineService', and it works once.

[bazilsafronov]

I faced the same problem. Version 1.12.1
It just helped me to reinstall the client

[ukarshiev]

Sorry, we could not configure your system to connect to Outline. Please
try running the installer again. If you still cannot install Outline, please
get in touch with us and let us know that the TAP device failed to
install with error code 1.

RU:
У меня была такая ошибка.

1. Я запустил Outline client от имени администратора
2. Зашел c:\Program Files (x86)\Outline\
3. Запустил файл add_tap_device.bat (от имени администратора)
4. В outline нажал "подключиться" -> подключилось со второго раза.

EN:
I had such a mistake.

1. I started the Outline client as an administrator
2. Zashol c:\Program Files (x86)\Outline\
3. Launched the add_tap_device.bat file (on behalf of the administrator)
4. In the outline, click "connect" -> connected the second time.

[raqeebhamza]

Solved it by downgrading to 1.10.1 on Windows 11

SAME.
I use 1.10.1 on W11.
Not letting to update.
Waiting for fix.

[cup-of-Aygiz]

the problem remains fix it

[Mikhail-behemoth]

Solution is here Jigsaw-Code/outline-apps#1007

[andr-c]

This one has helped me on Ubuntu:

systemctl restart outline_proxy_controller.service

[D-side]

I started having the same issue after going on a mild organization spree and renaming my network adapters a lil bit.
I was not expecting the Outline client to actually rely on these internally, these always seemed to me like human-oriented labels, but alright, lesson learned, can't do that with Outline apparently.

Renaming the respective interface to outline-tap0 fixed it in my case.

[ZNS05]

Hello everyone. When I distribute the Internet from my phone to my laptop and turn on OutlineVPN on my laptop, absolutely all sites in all browsers (Chrome, Edge) stop loading. He writes that "the site unexpectedly broke the connection" or "the site did not send data." I looked through Wireshark, packets are coming, the Internet is working. The Telegram application is quietly loading on a laptop. My telecom operator is Megafon. If you have met with a similar problem, please write back.

[D-side]

@ZNS05 this does not seem to be the same problem as outlined in this issue, I suggest you file a new report for yours; but before you do that, try to rule our your ISP as a possible cause, as this may very well not be a problem with Outline and might just be your ISP interfering with the connection. (Russia is currently cracking down on various censorship circumvention methods, Outline is most certainly on their list of targets and cellular carriers like Megafon are usually the first to start employing new censorship tech.)

---

(Russian translation for convenience)

@ZNS05 это не похоже на проблему, описанную в этом тикете, рекомендую для вашей проблемы создать новый; но перед этим постарайтесь уточнить, не связана ли проблема с провайдером — проблема может быть не в Outline, а во вмешательстве провайдера в соединение. (В России сейчас активно охотятся на разные методы обхода цензуры, Outline совершенно точно есть в списке их целей, а сотовые операторы вроде Мегафона обычно первыми кидаются внедрять новые технологии цензуры.)

I have the same problem for a long time: if OpenVPN is installed on my PC, Outline gives the following error when connecting: proxy connection failed to connect server undefined. cause: error: errpr invuking remote method 'outline-ipc-start-proxying': error: unknow nativeerror. No reinstallation has helped.
But I found a sudden solution that worked equally well on my home PC, work PC and laptop.

I assigned the name outline-tap0 to the TAP-Windows Adapter V9#2 connection in the adapter parameter settings. After that both Outline and OpenVPN raise the channel without errors, everything works.

Try it and don't forget to reboot your PC after renaming the connection, just in case )).

[D0BRIAK]

Just now saw that D-side above described this method)))))

It wokrs for me as well. Thanks!

[kiberli1960]

My outline-tap0 was simply disabled. When I started it again, everything worked.

[iftsv]

hi there,
Got the same error on Win 11

error invoking remote method 'outline-ipc-start-proxying'

I also have installed OpenVPN + NordVPN for another VPN connections and have another TAP connections.
I work under user account without admin rights. I feel that during Outline installation, the required network connection was not added. To fix this issue:

1. Open cmd.exe with admin rights,
2. Go to C:\Program Files (x86)\Outline
3. Run add_tap_device.bat
   ...
4. PROFIT!

[HiradNikoo]

Update the client app. If there is not other latest version then check (on windows) Event Viewer > Windows Logs > Application

In Event Viewer I had the "pipe is broken" error. But I updated to the latest version and it got fixed.
Latest: https://github.com/Jigsaw-Code/outline-apps/releases

[dmitry-js]

This happened to me after I installed NordVpn. Then I reinstalled Outline and it worked again

[acebiscuits]

had the same problem. in my case I just deleted outline and installed it again and it works now
