CANNOT LOGIN TO my katalon account

when launching katalon studio, I enter my account name and password, but it keeps saying my login/password is wrong.

I cannot launch katalon. Please help!

Do you have any special, special chraracters in your Password like for example: ’ , # , " , or even german umlaute like üöä i think can make it so katalon cant log you in

Same problem i am facing for version 6.1.0

it is working now to login to my account.
Katalon, please check why it didn’t work yesterday. I think it’s something wrong from your server when trying to validate user account.

i have same problem, when i shutdown my mac and start again, suddenly katalon request to activate (my katalon already activated before), and i input my valid account but error my login/password is wrong.
