I noticed the server was running at >90% memory so I decided to add a gig of memory. After rebooting Jira no longer works. Error 521: Web server is down.
When starting or stopping Jira with:
Everything looks normal. Jira appears to be running but there is no web access. There are no errors, there is no information about what is going on. Nothing was changed whatsoever except upgrading the server from 2GB memory to 3GB, otherwise the configuration is identical.
How do I fix this?
This is Jira 8.2.3
Running on: CentOS 7.5 x64
