When PMS starts on windows 10 or 11 internet drops

Server Version#: Latest

I have been running plex without any real issues for around 9 years maybe more, but I am not sure what the issue is now. I moved my server from a WIN10 machine to a WIN11 machine because the 11 is an Alienware with a strong GPU. Once I did that everything went to crap. Could not get internet on that machine anymore. Could not figure it out. Wiped the machine clean and the internet has been fine for a few days so I thought since there is nothing on the machine I would download the PMS and try again. As soon as I started the server, internet was gone again. I shut down the server and I have internet. I then tried to go back to the WIN10 machine and restart my server there and when I restarted the server, I lost internet there as well. WHY!!!??? What am I doing wrong?

there is a known issue with Xfinity CenturyLink routers and their security software that triggers with Plex
