I updated my small instance, it worked great. Until I rebooted the server then it stopped working entirely. I tried restarting the database and the app separately, but it never came back up. I had to wipe and reinstall as downgrading didn’t work either. Due to issues with names no longer federating if the instance is recreated with the same domain and name I had to change my subdomain entirely as well. If for example a user was named [email protected] and you reinstall that instance using instance1.tld. If you recreate the user [email protected], it will not federate any comments.
I may be a small use case, but it has made sure I’ll be waiting a good long time before upgrading again.
