Ever since I started playing 1.17 whenever I join my Realm I have about 10 minutes of playtime befor said error occures and the conncetion ends. Attempting to reconnect is meat with the error immediatly. Restarting my PC only gives me another 10 min until the next dissconnect.
Also there seems to be mutiple people having this issue on reddit, without a solution so far:

SocketException: Connection reset simply means that a TCP RST was received. TCP RST packet is that the remote side telling you the connection on which the previous TCP packet is sent is not recognized, maybe the connection has closed, maybe the port is not open, and something like these. A reset packet is simply one with no payload and with the RST bit set in the TCP header flags.
The following are possible causes for the error:
More commonly, it is caused by writing to a connection that the other end has already closed normally. In other words an application protocol error.
A Reset (RST) packet is received from a remote machine and interrupts the established connection. The sent RST packets may indicate that the TCP packets sent are not recognized, a connection between the local and remote machine is broken, or a particular port is closed and is not allowing for communication.
The TCP (Transmission Control Protocol) socket is closed because the socket received a close command from a remote machine.
The other end has deliberately reset the connection. It is rarely happens, and generally incorrect, for application software to do this, but it is not unknown for commercial software.
It can also be caused by closing a socket when there is unread data in the socket receive buffer.
