Why can't I find the server I just previously played on in gmod?

I recently played on a server on gmod that I really enjoyed, and I cant find it in my history. Can anybody explain why? I dont think the server shut down because I couldn't find it in the legacy browser while I was in the server...

Solution 1:

This is maybe a bug or the server is located somewhere else. People also have problems to find the favorites on the new GMOD server searcher.

Click on "Old Serverbrowser" and then open up history, you should find the servers you currently played on. Maybe you also see servers from other games too.

Solution 2:

There are the options "Server not full", "Has users playing" and "is not password protected", which filter the list. Unticking them shows all entries.
