IP Reputation Attack Shutting Off Internet to Device

Hello,

I recently started hosting a Minecraft server and port forward through the app from my desktop computer. When starting the server, I had turned on XFi Advanced Security. When hosting the server, my ethernet to my desktop device was shut off and I noticed there was an alert in the Xfinity app telling me there was an IP Reputation attack. I restarted my computer and tried again, but the same thing occurred.

I turned off XFi Advanced Security thinking this would stop the detection of IP Rep Attacks and thus not shut off the ethernet to my device, but now I just lose connection and no notification of an attack (since XFi is off). I believe the router is shutting off internet to my device to keep it secure, but I have firewalls, windows defender, and a whitelist to my server. 

Is there anything I can do to try and fix this issue? I have to shut down and restart my computer anytime a threat is detected. Please advise, thank you!
