I tried to assign the new certificate and this error is returned. It seems that wincc stores this data somewhere, but where?. It is strange that you cannot modify this port certificate. Any ideas? Thank you very much! Attachment certificate.JPG (282 Downloads)

In that case, I recommend you to install the update 17 because it includesmprovements in certificates generation with REST. You can check it here: Updates for WinCC V7.5 SP2 and WinCC V7.5 SP2 ASIA Good luck
