    I have problems trying to stablish a connection to the PLC. In my case I am following the tutorial on "Your first Codesys program" and using my laptop to simulate the plc.

    The gateway find the computer but always request credentials.

    So far I have tried to start Codesys as admin. I also tried the passwords Administrator (biz.) and Admin or admin without succeeding.

    Any idea what could it be the problem? How I can get around to remove the admin rights or credentials to the device?

    Both gateway and PLC have been started on the sysTray.

    But reagardless what user/pass wd I try I always get this error: "Invalid user authentication on the target" (See picture)
