The battle.net app starts without a problem, but the starcraft app repeatedly kicks me back to the login screen, multiple others have posted about this

After opening battle.net and launching starcraft, it loads, then, the “connecting” thing pops up, longer than usual, before it kicks me back to the login screen. I enter my data, it loads, but then kicks me back again. It seems to work at random intervals, mabye one in 4-5 attempts allows me to log in. This problem combined with the already stated “crash after game end” issue is making playinng SC impossible.
Other posts, all today or within 1-2 days, all after the most recent patch.

This was happening to me yesterday on 2 separate Macs. Just tried this morning and seems to be working again. Restart Battlenet just incase.

This has been happening to me as well.

It takes several failed attempts before I can log into SC 2.

Tried restarting Bnet app and it worked for me.

Just figured it out. Close battlenet and starcraft. Open Activity Monitor - there’s a task called Agent with a BZ logo. Force quit it. Launch battlenet again. Should be good.
