I get the usual error message " internal exception java.net.socketexception connection reset " whenever i try to join a 3rd party server, apparently only in aternos hosting services. I searched about it but i only found people getting this same issue but constantly, the problem is that i get it just ONCE (first time I try to join) and then it is no problem anymore, until the server is restarted or something like that.

I was wondering why would this happen just once because I'm scared it could happen permanently. The solutions to the "permanent" problem I've read are mostly useless in my case because I've set to 0 my pc couple times and it happens to me since like 1.20.1 or so.
