Updated to latest version of JetKVM - 0.4.3. I noticed under Settings -> Access there is a new setting for HTTPS Mode (Experimental).

Just wanted to report that I tried to test with my own custom certificate (it's a wildcard cert for my domain). I put in the certificate information and the private key, but when I press "Update TLS Settings" I get the following error:

One of the things I did notice that in the "sample" text for teh Private Key, you have

START PRIVATE KEY
END PRIVATE KEY

When my key file starts and ends with

START RSA PRIVATE KEY
END RSA PRIVATE KEY

Not sure if that's the issue, but not sure what's causing the issue. I can't save or update the certificate.
