So you did skip a couple versions of 5 in the process, which normally may be kay, but sometimes it causes bad things.

Did you happen to have any ssl setup before the upgrade, specificaly on any inputs?

I don’t think I setup any SSL on any inputs, Going strictly by memory here since I can’t login to the Web GUI to verify.

Is that the only error in the logs

Also did you confirm mongodb and opensearch are still supported versions?

So when I originally realized that the upgrade failed, I went back to a previous version. Unfortunately, at first, the error persisted and I thought the installation was doomed. I left it running hoping the problematic logs will eventually go away and to my surprise I was finally able to login and it all seems to be working. I’m on version 5.0.13 currently which is the version that it originally was before the failed upgrade.
