True, I have found some cases too.

There has to be an issue with the login of some sort (user-defined passwords, special characters in old passwords..).
I sure didn't go out and change all my password copies, original, backups, password managers backup, password managers, URLS on 2 computers each 2 browsers because I was bored, and wanted to lock myself out of my account!

I am spending my time to go over their commits on github repo for any clues...

Keep us updated.
I've only got 1000 BTS on the line ( the incorrect password error in my first account on Openledger DEX )
The new DEX account I made today seems to work, but I probably won't send any BTS to it unless the first account becomes accessible again.
