Error loading discovery document: Autoquotes

I have seen this issue in the past and I have resolved it by restarting the internet connection, but I have an Autoquotes user being stuck and unable to reach the login screen of the AQ CPQ app for the past 3 weeks, I was wondering if there are some settings or suggestions I can provide to the IT to establish a connection with Auth0, this is for Windows 10 Pro.
