I try to update umod to the newest server version, it says successful, but whenever I try to join my server it states I need an update. How do I fix this?

umod is not a 'client'. There is oxide and there is umod.. most people use oxide. A server would not state anything about oxide versions. It's probably telling you the server itself needs updated.

Doesn't Umod include a server update feature? I ran that and it didn't work either. I'm not exactly sure what you mean by the umod/oxide description btw

distinction*

Oxide is what you download from the Games page, uMod is unreleased and isn't installed the same way. There is no server updater with Oxide, only with the uMod Agent. Using uMod isn't recommended for a live server at the moment, as it may not always be up-to-date as it's only intended for testing.
