I reinstalled WOW, did all official suggested Blizzard steps, same problem. When I go to EU server where is 11.1.7 patch, its downgrading and letting me it, as soon as I go to US server it updates to 11.2 and this error pops up.

So tired of this, if Blizzard don’t fix it I’m cancelling all my subscriptions.

Patch isn’t live in the EU yet.

Yes I know that’s why I mentioned that logging in to EU I have no problem, when I go to US account I see it upgrading to 11.2 and this error pops up.

Did you use a VPN?

I flushed and changed DNS (Google, Cloudflare), rebooted, disabled firewall and antivirus, cleared Battle.net cache, reinstalled Battle.net and WoW, tested with VPN (US East), tried direct IP in hosts, confirmed US patch/CDN URLs open in browser, ran tracert (route is fine), but WoW US still fails with WOWDOWNLOAD_COULDNT_RESOLVE_HOST while EU works fine.

Did you mean these steps?

Yes correct

Are you out of space for the update? Not sure what else would cause this hiccup, have never run into myself to troubleshoot.

500gb Free :slight_smile: I’m still doing 99 steps with CHATGPT for the past 5 hours :smiley: But the Blizzard the ones who must fix it asap, I created a ticket as well.
Thank you ! I appreciate it
