When I went to see my confluence, I saw that it was not available and that it gave me the following error:
This page is for Confluence administrators. If you're seeing this page, your Confluence administrator is probably working to restore the service.
|Non Clustered Confluence: Database is being updated by another Confluence instance. Please see http://confluence.atlassian.com/x/mwiyCg for more details.||2022-08-24 03:02:33||fatal|
This means what it says - you've tried to start a second instance of Confluence Server pointed at a database that is already in use by an existing Confluence Server. (This may actually be the same physical install, but it's the second process that won't work)
You'll need to check the configuration of your Confluence, identify where the first one is running, and either use that, or shut it down and start your instance.
