Use proxy with ConnectTimeout

[Mystic8b]

Greetings, friends.
I couldn't find a good solution for using a proxy when the machine is offline.
I tried doing this:

    except ConnectTimeout as c:
        apihelper.proxy = {'http': envsettings.tg_proxy, 'https': envsettings.tg_proxy}
        _send(text=message, effect=effect_id)

But in this case, the proxy will be used for all subsequent messages.
If I add apihelper.proxy = {} anywhere, it causes a multithreading problem (in the main program code). While one thread disables the proxy, another is still relying on it, and some notifications are not sent.
I thought about it all day yesterday and couldn't find a nice solution. Of course, I can check the internet availability on the machine in a separate process, but it doesn't seem like the best solution to me.

I don't think we can do anything about it. Proxies are usually used fully or not used at all
