BLZBNTAGT00001398 11.1 Update (SOLVED)(?)

Unable to update to 11.1 of World of Warcraft, after numerous attempts at fixing the issue, which include

Running in Admin
Deleting App Data
Closing Riot Vanguard
Restarting Computer
Ending all processes prior to restarting Battle.net
Reinstalling Battle.net
Reinstalling World of Warcraft

Looking for advice if anyone else has run into similar issues and or solved it, or looking to support grievances of others running into the same issue.

Miraculously after a meticulous 14 hours of attempting to fix this, it has fixed itself. No clue which of these solutions helped (if any at all), if experiencing the same issue, attempting to go through that list top down might end up in success.
