Me and my wife have been playing MC on Lan for a couple years now, and ever since we updated to 1.17.1, we fail to see each others LAN servers and even a direct connection is lead with a time out. We tried all the trouble shooting techniques such as disabling antivirus, resetting the WIFI, restarting computers, all the way to reinstalling network drivers and making AP isolation is off. At this point we have come to conclude that there is an issue with the update. If anyone were to have a solution for this, it would be much appreciated.
