I have uninstalled/reinstalled Gmod, verified file integrity, and backed up the game. 
The theory presented by Dinkleberg is that I have a dynamic IP which happened to change to an IP that has been banned. 
I appreciate the advice offered.  This is basically a waiting game for the IP to roll again. Feels like a DnD moment saying roll again.

Have a blessed day.

I doubt this is the issue. There are 2^32 IPv4 addresses. The odds are so low that you accidentally got an IP address of an IP banned player. Go unplug your modem for like 15 mins, it should get you a new IP address; it’s more likely the unplugging off this will fix it and not getting a new IP address.

Speaking of which, can I just say that permanent IP bans are really, really dumb? Do people not know what DHCP is?
