Unable to connect online

I am having the same issue. I just reset my password, but have not logged in for about a year. Not sure why I can’t get access to battenet.

tried the switch to beta (no luck).
Deleted the test file (worked)

Deleting the public test file also solved the problem for me, which begs the question why install the files in the first place if it keeps the game from working? I have not played Blizzard games in years and I am already remembering why I stopped.

The beta didn’t work for me and I don’t have the test file. Any other ideas?

I tried to connect now nad still doesn’t connect, it says Battlenet is down for maintanance, this error is taking for a few days, it will resolve by deleting Starcraft II Public Test.exe in Starcraft II folder.

u suggestion doesn’t work.

So to clarify, SC2 is saying there’s a maintenance and you have already tried a clean reinstall of the game through the Blizzard app?

So to clarify it works now, imo it was hardware problem : I was using an old Samsung monitor. SC2 doesn’t launch or or can be played on that.
I got my Dell monitor back and is working. Tried to swamp them - same problem.
Before that I tried cleaning, repairing, unistall , connect without internet conexion , nothing worked for me.
The SC2 was there minimise in the windows tray barr.
Blizzard didn’t said anything about service- maintenance.
thx
