My internet does not work with blizzard for some reason

My friend and I have been experiencing several issues regarding blizzard and its games. whenever I try to open the website or the app on my pc it does not connect and just loads for a while. Some of the games like COD MW are not accessible because of this. During the beginning when the blizzard page worked for a bit I still could not access COD Modern Warfare. However, when I use a VPN or change my internet connection from my main one to my mobile hotspot, it works. This would be fine if not for the poor internet and poor in-game ping. I have tried restarting both my router and pc, factory resetting my router, and changing the DNS to Cloudflare’s. It has been a couple of days and I honestly do not know what I should do know. Any and all help would be appreciated.

If you and your friend are on the same ISP then it could be there’s a more local issue you may want to talk to your ISP about. However, we can also take a look at your system files to see if there’s a problem we can identify that could cause this.

Can you connect to the Battle.net App? Or any of our other games?
