Unable to install Battlenet (Error: BLZBNTAGT000008FC)

I have been trying to install Battlenet and each time gives the same error after it gets to 45%. I tried every fix I could find on the internet, I tried to run as administrator, I changed to a mobile hotspot, I disabled the firewall and windows defender, I resetted the WMI depository, I even tried to install the Chinese client as it worked for some people. None of them worked.

Unfortunately I cannot post the logs, as they contain links, but I would be happy to provide them to any samaritan that wants to help (as a quick preview of the logs, there is this line: E 2024-09-01 06:23:21.250766 [BSAgentManager] {1f78} Fatal error occurred while updating: 2300) . At this point any desire to play WoW is melting away with each ‘unexpected error has occured’.

I would appreciate any help, thank you.

Did you change the region in the data files too?
