Mac - BLZBNTBTS00000029

It will not even let me install the Battlenet app.

I have done all the suggested self help fixes. No go.

Any ideas?
macOS Big Sur v 11.2.3

Howdy Thumperness,

This typically indicates something on the computer or network is blocking the connection to the patch servers. Did you try disabling the firewall temporarily?

If so, please reply with a full list of steps so we can get this further investigated.

I also am having this issue and have tried. everything. firewall currently turned off. I keep trying to start a ticket and am getting very frustrated. It has been over a week.

Howdy FrostyFeet,

Does the problem persist on an alternative connection or VPN? If it persists, these steps may help with the issue.

I’m having the exact same issue on my Mac OS Big Sur 11.2.3.
Uninstalled early this morning due to Retail WoW not updating properly. At this point classic WoW was still running. Deleted the battle net app and all WoW files. Reinstalled only to find the BLZBNTBTS00000029 error code.

I’ve tried restarting the computer multiple times and deleting and re-downloading the battle net launcher without success. I also tried downloading World of Warcraft separately which showed the same error. Filevault and Firewall are disabled. All background applications are shut besides the battle net installer. The link for alternate download is for windows, thus it does not work. Checking the host file is also for windows, so does not apply. Testing another computer is not an option. Tried creating another admin account and this did not work either. Frustrated as well as I just bought 3 months of gametime before everything stopped working. Not eager to have it waste away as looking back in threads of this same issue happening with other Mac users, the problem was never resolved.
