Password reset and accountmanager problems

I try to change my password through the dashboard webversion, but it keeps saying “Actual password is incorrect”, but that is not right, I did autofill and by hand, but notitification incorrect stays.

(I would like to change password, to see if accountmanager issue can be solved deleting murena account in accountmanager and then adding back again and changing password: Murena Account Authentication Failed (Every other day))
