Since today, it is not possible to connect to any repository with any user or any pc. I have tried to access the repositories with different users (with different ssh credentials), with different PCs and different repositories. https-access is working so far.
Yesterday, the ssh access worked without problems. As there was no software update on the server in the night, I have no clue what could be the reason. As the access problem exists on all clients, I think it must be a server issue. Therefore I tried to upgrade to the newest bitbucket software. The upgrade worked perfectly so far, however ssh access is still not possible.
According to netstat (sudo netstat -plnt), the port 7999, the port is listened.
tcp6 0 0 :::7999 :::* LISTEN 3683/java
Has anyone any hint, why the ssh access is not possible any more?
This is the result of the console:

I found an interesting log entry, however still no clue what happened:
c.a.b.i.ssh.server.SshCommandAdapter git was successfully authenticated via public key, but is no longer active in the underlying user directory. The request has been blocked
So that seems to be the reason why no ssh access is possible. It seems that there was no connection to the jira server for a longer time (seems to be ssl problems) and that therefore the accounts have been blocked.
Found the reason why no ssh login was possible any more.
The bitbucket server was connected to jira, however the ssl certificate was not trusted (the jira certificate was not in the truststore of the bitbucket server). Thus, no user directory synchronisation was possible. Bitbucket blocked now the ssh login. Reanabling the user synchronisation fixed the problem.
