Hey,
i’m trying to set up a Keycloak Server in Development Mode. Everything worked fine following the Documentation → OpenJDK - Keycloak
Now i would like to configure TLS / HTTPS and test the import of my Certificates, as changing the HTTPS Ports.
If i follow the Guide to it Configuring TLS - Keycloak i assume that the command “kc.sh start-dev --https-certificate-file=/path/to/certfile.pem --https-certificate-key-file=/path/to/keyfile.pem” should work.
But i get an Error that says:
ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: Failed to start server in (development) mode
2022-11-11 11:43:34,421 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: Unable to start HTTP server
2022-11-11 11:43:34,421 ERROR [org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler] (main) ERROR: java.lang.RuntimeException: Missing -----BEGIN PRIVATE KEY----- or -----BEGIN RSA PRIVATE KEY----- or -----BEGIN EC PRIVATE KEY----- delimiter

I tested it with a Self-Signed aswell as with a Enterprise Certificate. Both the same Result.
Do you have an Idea what the Problem cloud be?..Probably something small and stupid 
The Files are all readable with cat and it seems the Cert is 100% ok.
Thanks and Greetings
