Solved! Go to Control Panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change settings. Scroll down the list of applications to CODESYS and CODESYS ControlService. If you do not see this application, add it to the list. Make sure all checkboxes are checked (Domain, Private, and Public).
I have the same problem
Sorry Eschwellinger, but the October release is the one that doesn't work... TY Davide Pilia
