Unknown Error Occurred While Trying to Join that Server Message

[Deleo]

I've tried both things between rebooting my computer, usually after not playing for 30 minutes I can play again but it happens again. As far as reinstalling I don't think that will fix it, because this just started happening in the months that I've been playing on p99. Also this happened to an enchanter I was with he got the same issue that I was having then it happened again to both us this was the incident while I was in steamfont
