Hi,
The internal browser is a JavaFX browser. I'm not sure if websockets can be disabled in JavaFX or not.
You can try the following to enable https with REST discovery:
Add the certificate to the JRE cacerts file located in <SoapUI Pro install>\jre\lib\security (please back up the file original first). Add the certificate with the following keytool command below, the keytool is in the jre bin directory.
keytool -importcert -file <your certificate> -keystore cacerts
Then restart SoapUI and try to use REST discovery.
