Hey guys, I have have tried for many hours to fix this issue, But I cannot connect to the PLC-Sim anymore on Factory IO. It has worked flawlessly for over a year while I’ve been in studying (We have used TIA18) - But now it doesn’t work anymore when I try to connect, I have also tried with TIA portal 19. I’ve tried to also re-install all the programs, and checked the licenses, but when I press “Connect” it says "Error Code : -4, DoesNotExist
I can modify the program in TIA portal without any issues, but got no connection to FactoryIO. Any suggestions?
