Well, that tells me your connection and path to the server(s) is having issues. Meaning you are getting knocked offline from them.
Could be anything between your device all the way to the server. Your connection routes though a LOT of hardware between you and there and through multiple companies/ISP routes, backbones, etc.
Its fun having to rely on a whole lot of things to make this work, doesn’t it?
Seriously though, there is no certain way to know what the issue actually is. It may be temporary, could be a local ISP pathing issue, no way to know for sure.
You can try to run some network tests and see if you find anything from here:
-For everyone having connection issues of various types: UPDATE 8-7-23
See if those find any issues with your internet/path.
