There is a limit of concurrent CLI sessions, this is listed in the release notes, for RP 4.1.x it's 100 per RP cluster. It isn't limited to a certain user. Not sure which version of RP you're using but you can change the password through the admin user as well. The change should be propagated immediately but there were cases in the past where the GUI session must be restarted with the new password to operate smoothly. in your case, it's possible the admin user have been locked because of the wrong password being entered. You can unlock the admin with the unlock_user CLI command via security-admin.  Regards, Idan
I tried to change the default admin password and it seems to be flaky for both ends of my RPA's... Are you supposed to change it in under the security-admin user? Then all of a sudden the new one worked in the GUI but not for the command line... Luckily I am logged in and tried to login on a third screen to no avail... Is there some kind of limit of users logged in under admin? I was thinking it might take some time to propagate but that doesn't seem to be the answer either...  Thanks
