Basic Info :
I am using Codesys Control For Raspberry Pi SL. Version 4.4.0.0
Engineering version : CODESYS V3.5 SP19 Patch 1 (Its a old application)
I am facing a difficulty with the "Device User Logon". The window (screenshot attached) pops up during login. When i enter the credentials (which i feel are correct), the windows pops up again no matter how many times I enter.
To ascertain, I tried entering the incorrect credentials during which its clearly specifying that i have entered them incorrectly (which is why I am quite certain about the credentials being correct).
I even tried going into Communication Settings > Device(drop down) > Change Runtime secuirity policy . However it again asks me for credentials which keep popping up again and again.
I am thinking of upgrading the runtime to the latest version of 4.20 Will it cause any issues with the paid license?
Thanks for your reply @eschwellinger. Update : the is problem is resolved. It was done by renaming the User database file (/var/opt/codesys/.UserDatabase.csv) as deleting it was risky. After restart the IDE asked me to create new user. On doing that the problem got resolved.
Reference for members facing similar problem/s :
sudo systemctl stop codesyscontrol
sudo mv /var/opt/codesys/.UserDatabase.csv_ /var/opt/codesys/.UserDatabase.csv_.old
sudo systemctl start codesyscontrol

Please suggest me a solution.

Hi Suyash,
if possible update to latest CODESYS version.
license should work version independent.
