on premises data / Excel Power Bi publisher desktop connection

Hello

I’m having issues getting either on premises data gateway or Excel Power Bi publisher to connect / sign in. I’m getting odd network errors. Bear in mind, I’ve got all firewalls off. From on premises I get the following error when I try to login using my email. Note, I can sign into https://powerbi.microsoft.com/en-us/ with no issue. Below is the error I get

Network request returned unexpected error.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 157.55.171.53:443
at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult)
at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)

I’ve installed the most recent version of .net as well as reinstalled both on premises and Publisher, multiple times. It appears I’m having an issue with some kind of service that supports the login from the desktop app back to the data gateway. This problem exists in power bi desktop as well. Help. Desperate for this to start working. Thank you in advance.
