I upgraded Confluence to the latest version and now on startup I get the error logged below. Confluence will come up in the browser but only in a 'text' mode.
The exception UnknownHostException: is raised for a server that no longer exists and didn't exist when the upgrade was done. But now it throws the following. I can't find any reference to the server in configurations so wondering how to resolve. Any ideas appreciated.
