New Patch Download

This new patch is downloading super slow for me. It was downloading fine at first but now it’s going very slow and says I’m downloading at 0bps. This happened when 8.1 came out too.
UPDATE: now I’m getting an error that simply says “Whoops! Something broke! Give it another shot” and cannot make anymore progress on my download. Excellent.

Same thing happening to me. I went through the troubleshooting steps and it still does it. Repeatedly clicking ok on the error and starting the update again works eventually but it gets stuck at 0 B/s soon after

I am having the exact same issue, have done all the normal stuff to try and fix it, disabling firewall and defense programs, I always run battle.net in admin mode, have tried the repair tool and still getting this.
