I’m having some issues push/pull/clone with my ssh key and I’m not sure where else I’m supposed to look for troubleshooting.
I’m running Gitea 1.26.2 in a docker container with ssh forwarded to port 222.
I’ve uploaded and verified the key I’m using, but I keep getting permission denied (publickey)
This is what I get when I run ssh [USN]@[URL] -p 222 -vvv
❯ ssh [USN]@[URL] -p 222 -vvv

This is what is says on the docker logs:
Accepted publickey for git from [External-IP] port 42032 ssh2: ED25519 [Redacted SHA]
Received disconnect from [External-IP] port 42032:11: disconnected by user
Disconnected from user git [External-IP] port 42032
I am using ssh on 22 for the machine, but ssh for Gitea is running on 222. I suspect it’s an issue with those running concurrently, but I’m not sure how to remediate it.
Other users are using https to clone fine, and I’m not sure what other logs I can look at to figure out what caused this. Thank you!
