Hello.

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?

Please suggest me a solution.

BR,
Suyash

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