I can't enter the game or the website using mobile data

(I'm writing this from a different wifi) I always connect using my mobile data to play wow...everything normal...until I stopped playing to go to eat and when I came back I couldn't enter the game EVEN Web page. wtf!
When I enter my data in the game, everything freezes and says: "could not connect, try again later"...and if I try to enter the website, it says: "DNS_PROBE_FINISHED_NXDOMAIN"...
...
Things I've tried:
-I'm not banned
-The Reamlist is written correctly (in case anyone asks)
-I use 4g
-Pc and mobile turned off and on again without changes.
...
I don't know what to do...it's just that Warmane website doesn't even enter...that's what makes my head explode.

HELP!!!!

It sounds like your ISP has blocked warmane.

I have sent an email to my ISP to see what happened... but it will take days for them to respond... and in the meantime without being able to play :C
There is a remedy on the internet that is based on bypassing that "block" using a VPN...but if I use it, Warmane blocks my account...hahaha I'm screwed

Now mysteriously I can play again... I don't know what the reason was.
