Re: unable to connect to the servers

Hi, It's been 2 days and I can't log into my account in game on Xbox Series X when using WiFi connection from my ISP (Indonesian ISP : Ideanet). But, when I use connection from my phone network via tethering, I can log into the game and there are no problems. How can I fix this? 

I've tried everything from resetting the WiFi setting on my Xbox, restart my router and Xbox, and use Google DNS but no luck whatsoever. The NAT on my Xbox is already Open and I still can't log into my account. Please help
