None of my keys is accepted for login.

Not even your Owner Key? It's very strange!
I hope you are not using your public keys and inserting private keys only.
If it's working for logging into Steemit, it must work in SteemConnect too.

Nah, I was trying with my Master key. And then I tried with all of my keys. None is working for me.

I don't see any reason for Master Key not working!
Try after some break ..may be tomorrow or better still, put your complaint in Busy's Discord. They may know the problem better.

So when u use steem-connect u cant log in?

That is odd. I have tried this with several accounts and working well for me.

You need to use the active key when u log on.
