I attempted to push to ssh://git@gitea.leexxx.com:61222/sinlee/openclaw-sync.git but got connection closed.

Please confirm:
1. The repository name and owner (e.g., sinlee/openclaw-sync)
2. Whether the repository is public or private
3. If there's any different URL you used when creating via web UI (sometimes the path includes a different username or group)

You can also try running this command to test access:
ssh -T git@gitea.leexxx.com -p 61222

It should return a greeting with your username.

If the repo exists, we can also try to fetch from it to see if we can read.
