Hello Mojang-Team,

a couple of friends and I started a 1.17 MC-Server. All my friends can join just fine however everytime i want to join i fall through the map and then i get the "java.net.socketexception: connection reset" error message and get kicked from the server.

So i have tried multiple servers. Everytime i get this error. When i can manage to stay for some minutes i have a terrible ping.
It can't be my connection. i have a 47 MB/S download on steam, all my youtube videos load in an instant, etc.
I even tried to deinstall and reinstall minecraft and java 16, tho it didn't work.
I've tired to deactivate my firewall and it didn't work.
I have an up to date graficcard driver and i deinstalled and reinstalled minecraft like the support said. 
 
However i have no problem too log into the launcher itself or to the mojang website.
And i can play the single player just fine. 
I am only unable to join on any server properly. 
 
Maybe you can help me to fix this bug.
Thanks in advanced
Geron.
