Bnet connection issues

Hi, I have been having an issue connecting to battle net for two days now.

The Battle net app Logs me in but is stuck on “connecting” additionally the battlenet website does not open either it just says "ERR_CONNECTION_TIMED_OUT“

I have tried:
DNS flush
Using an alternative DNS
Reseting my touter
Updating my router

I believe it has something to do with my ISP because if i use my phone data i can access battlenet.
Please help me i have just bought MW2 and i cannot play it.
