internal exception java.net.socketexception connection reset

Ever since I moved to a new residence and swapped from AT&T to Comcast for internet using my own Modem/Router, I've been having issues connecting to my realms on Minecraft, single player is fine, only the realms portion. Sometimes I can play for an hour, sometimes its only seconds before I get kicked off and get a socket exception error, before it used to say "connection forcibly closed by remote host". I've got solid internet @ 400mb/s, ethernet wired, the only realm difference is I'm using my own modem/router I guess. I am not sure if the issue started with 1.17 dropping because this did happen around the same time, but I had not played Minecraft for a while until I moved to a new home so I cannot reference whether ISP changes are the issue or if it is a Minecraft server issue. I've done so many methods to try to fix this I've lost count. Any information is appreciated as Minecraft support states it is difficult to diagnose a issue remotely. the only thing I haven't actually done is deleting my realms servers and just restarting.
