Install Battle.net APP freeze at 5%

Hello.
I downloaded the Battle.net app and wanted to install it. It freezes at 5% and does nothing else.
I have tried on a fresh Windows 10 install, fresh Windows 11 install,
Fresh Linux Mint 22, fresh linux mint 21 and nothing works. It stops at 5 % everytime. I have reset my router i have tried the “reset dns thing” on tutorials on youtube and still nothing works… 1 day ago i could install the app on all those systems with no problems at all… What is going on?

SOLUTION FOR ME

If anyone sees this post… i figured it out… even though i reset my router it did NOT change firewall settings from high to medium… at high it blocked blizzard… so change to medium or go to logs and find out which port they use and unblock that port in the routers firewall… that was just what worked for me at least.
