My workaround to get an https connection is now: Change the config-file on server side to: <WebServer Enabled="true" Urls="http://:8624;https://:8625" CertFile="C:\temp\emea-ci-cd-01.pfx" Password="xyz". (pfx instead pem). Nothing change on webserver. Then https works. But webserver shows now an error.

It is a not so nice solution but I can continue like this for now. What it really was or is, I don't know.

Diagnostic Center shows follow error:

Failed to load certificate for HTTPS connections. The key contents do not contain a PEM, the content is malformed, or the key does not match the certificate.

System.Security.Cryptography.CryptographicException: The key contents do not contain a PEM, the content is malformed, or the key does not match the certificate.

Certificate is accept:

And I can see configuration serverside:

Execution according to instructions: (pem craeted from pfx)

HTTPS Binding to a Port (Advanced) (Experimental)

I have checked the validity of the certificate. Does anyone have a hint or tip what went wrong here.

Change to https access denied.
Error by config "HTTP/S & Certificate Settings". Access denied warning when config will be save. Is there anything that i must be configure before?
