[Solution] Inventory and other UI freezing, found a fix after trying everything

Technical Support

Force allow the game through firewall (for some reason it didn’t add itself there) and block Blizzard cdn servers in Windows hosts file:

127.0.0.1 us.cdn.blizzard.com

i also added one for EU just in case

127.0.0.1 eu.cdn.blizzard.com

I’m on EU but for some reason when I open Inventory it does requests to us.cdn… and then times out. It’s written in the game’s log file called FenrisDebug.txt

They look like this:

E 2026.04.26 19:14:16.649381 528 [Sigma] [tact] [:0]: cURL request us.cdn.blizzard.com/blah/blah failed with 28 : Timeout was reached
E 2026.04.26 19:14:16.649390 528 [Sigma] [tact] [:0]: Download request us.cdn.blizzard.com/blah failed. Code: -1.

Now my inventory just hicks up once for a split second and then works flawlessly.

Not sure what spaghetti network coding Blizzard was using if blocking this does only good.

“hosts” file is here:

C:\windows\System32\drivers\etc

Win+R

paste C:\windows\System32\drivers\etc

Enter

open it with notepad

add lines

127.0.0.1 us.cdn.blizzard.com

127.0.0.1 eu.cdn.blizzard.com

Save

Restart PC

Works, nice, now are we sure by blocking local host we wont have any issues down the line?

No idea, someone from Blizz on twitter liked my tweet with a link to reddit with this guide. Maybe they’ll fix it on their end.

Very thankful for your post, at the same time highly disappointed by Blizzard.
