I don’t have VPN software running on this computer.

Update: Ok, I actually did have an instance of WireGuard VPN running on the computer, that I use when I’m out of the country to allow me to connect to this computer. It allows me to use Youtube TV and any other Geo blocked services as if I were still in the USA. Shutting that down (not sure why this would matter, though) allowed me to connect to the router. Thanks for jogging my memory on this, bOcy!
