Cannot log in to Starcraft 2, Battle.net always under maintenance

Got a new laptop at beginning of august 2020 uploaded SC2 and everything is up to date and yet I cannot play the game. I have tried numerous ways but when I log in to play it keeps coming up with Battle.net is down for maintenance.

How can it be down for a month?

We had a post tracking this over in the US forums, a number of solutions have been found, I recommend checking it out here.
