Two days after upgrading to 7.4.11 confluence does not start

[Ignacio Sola]

Hello.

We upgraded from 7.3.1 to 7.4.11 on Saturday but today Confluence server went down and now we are no able to get access to it. (connection refused).

I can see this message in the logs:

07-Sep-2021 09:40:53.512 SEVERE [https-jsse-nio2-443-exec-4] org.apache.tomcat.util.net.Nio2Endpoint$Nio2Acceptor.failed Socket accept failed

Kind regards.

Hi @Ignacio Sola , 

I would have a look if there are old Confluence processes running on the server maybe, as the error says that the port used by Confluence is already in use.

Have a look if you're able to check at the port used (usually something like 8090 or 8080) and if it's free on the server.

Let me know if this helps,

Hi @Alexis Robert , thanks for so prompt response. Your answer make sense to me, I'll try to check it before if it happens again.

I managed to run Confluence after a server reboot. I wonder if Confuence was faster than the "other" deamon :-)

Kind regards.

A server reboot did the trick for me too after upgrading from 8.5.5 to 8.5.8.
