Bad internet problem but internet works just fine

So I have some ok internet but OW whenever i open it it says ‘‘Sorry, we were unable to log you in. Time out communicating with blizzard services’’ same thing happens to other online games like Fortnite and pubg. I just have no clue to what’s going on, Fortnite and pubg say its internet problems, i can use the web just fine, i was playing some games like 3 days ago and it was working. But now it just doesn’t work.

Connection quality is important for online games with real-time action happening. Surfing the Web requires the most basic of connections, but you’re definitely having a quality problem with your service.
