This is also on a RevPi core III with the revpi driver package and codesys controls for rpi MC
I have encountered a bug or maybe I'm doing something wrong here. On codesys 3.5.17 I have created an admin username and password upon first device login as it said I must do. It worked well the first few times logging into the device. However, now when it prompts me to enter my credentials, it doesnt accept them and simply keeps requesting them over and over and over again. So now I cannot download a program to the device and I cannot change communication policy because I cant get logged in as admin....
