Custom Games - You have been logged out of Battle.net ERROR

I start a custom game and crashes once the game loads with error “You have been logged out of Battle.net. Current game is valid and results will be processed.” Then it exits me out of the game automatically with error: “You have been disconnected from Battle.net” with buttons to choose from “Login” and “Play Offline”.

If I click “Login” it brings me to a page to login within the client with 3 buttons to chooses from… after waiting a few minutes it brings me to an error: “There was an error handling you request. Please check your VPN”. Can’t even play the game with this…

Error 1: “You have been logged out of Battle.net. Current game is valid and results will be processed.”
Error 2: “You have been disconnected from Battle.net”
Error 3: “There was an error handling you request. Please check your VPN”.

UPDATE: Found issue is occurring 100% on Wi-Fi, was working 2 days ago. This issue only started happening all day yesterday and today. Can do Wi-Fi on everything else and network speed is good, 90+ MBps
