Connection problems when connecting by node id and region id

[rklaehn]

I have a very small request/response iroh service in https://github.com/n0-computer/iroh-examples/, specifically https://github.com/n0-computer/iroh-examples/tree/main/content-tracker .

It is a content tracker, but that is besides the issue. Basically you do a connection via node id and region id, then send a very small message, and get back a very small response.

I found that this does not work reliably without the inclusion of the ip addresses. The connection establishment and sending initial data works, but the response never gets through and the connection eventually times out on the sender side.

Sender:

❯ cargo run query --tracker jfnwg2wbgbgignugsmcl7vd2ywxkvjjkbw4sw7xdfv3mnpcsorgq bafkr4ih7kfrg3q323ujxli24ms4koorxchupucvbauuvfz7mlgzbixd2li

Error: read error: connection lost

Caused by:
    0: connection lost
    1: timed out

Receiver:

calling accept_bi
got bi stream
handle query: Query { content: HashAndFormat { hash: Hash(ff51626dc37add1375a35c64b8a73a3711e8fa0aa1052952e7ec59b2145c7a5a), format: Raw }, flags: QueryFlags { complete: true, verified: false } }
...

So the msg immediately gets to the receiver, but the response and/or the closing of the stream never arrives.

Disregard. It was just me being stupid with a lock. Turns out you should drop your lock before sleep.

Yep, this was just a stupid lock.
