Encrypted communication not possible, Device name 'XXXX' does not match the name of the certificate 'ctrlX-CORE'!

Hello,

I have a problem to conect my PLC Engineering to my ctrlX X3 (Version 3.6) and it looks like there is a Device name difference between the certificate and my ctrlX...

It is true, I changed the hostname of my ctrlX and I didn't regenerate the certificates...

How can I regenerate it, I suppose it is in settings/certificate/ but which one?

I also need to deactivate in Codesys the encrypte communication but I don't find where ?

How can I also re-insert the new certificates generated?

Thanks for your help

Hello,

Finally, I just found the issue it was due to the hostname I defined in my ctrlX X3 : DCET-FR-AE-NCY-X3. In fact, hostnames can not be in uppercase, only in lowercase : dcet-fr-ae-ncy-x3 . In this case the popup triggered a new certificate exchange and connection works 😄 :

Thanks for your help
