I never had any issues with it, but today, I have that : SSHException: Error reading SSH protocol banner This is strange because it happens randomly on any connections.

It could be ansible error reading ssh protocol banner network congestion, faulty switches, etc... but usually it means that the target server is bogged down or its sshd has hung. Recovery is to wait and try again. If you control the server, its a good time to check on its health. –tdelaney Sep 1 '14 at 16:49 1 You can reproduce this error by making 10 threads and opening/closing sftp connections as fast as you can on all of them.

The underlying cause, as pointed out in the comments, are congestion/lack of resources. In that way, it's similar to some HTTP codes. That's the normal cause, it could be that the ssh server is returning the wrong header data. 429 Too Many Requests, tells the client to use rate limiting, or sometimes APIs will return 503 in a similar way, if you exceed your quota.
