Intermittent SSH errors - 'Connection closed by' (BBCDEV-1775)

Issue #13032 resolved
Theodora Boudale staff created an issue

Some users have reported issues when cloning/pulling/pushing via SSH.

These operations sometimes fail with error:

'Connection closed by' or

'Connection to exited: Remote closed the connection fatal: Could not read from remote repository.'

We are currently investigating this as a bug.

    Also, the proposed solution of setting

    Host *
        ServerAliveInterval 30

    in ~/.ssh/config is not working.

    I'm experiencing the same issue with Mercurial repository.

    When I try:

    ssh -vT

    I get this:

    Hi Everyone, We have made some changes this morning that should solve some of your issues, and help us troubleshoot others. Could you run a few more tests, confirm if the issue is resolved or not for you, and if not provide some debug for us?
