Ssh connection deactivated after starting the startup script

Hello,
Since installing xwiki on my server, I can not connect to the server in ssh.I’m using a server running ubuntu.
Can you help me fix this problem please ?

Best regards

With the information you give it is hard to get a grip on the problem.

Can you connect to the server at all?
If yes, what is the output of systemctl status sshd ?

@ClemensRobbenhaar thank you for the answer.
I could find the origin of the problem. Ssh access on my server is disabled when I restart my server in ssh. I need to find a solution to correct this problem.

Best regards
