MC console certificate

Hi guys! hope you're doing great, I'm looking instructions on how to use my own certificates on vertica MC console don't want to use self-signed certificates ones to avoid add the browser exception I've checked this:

https://www.vertica.com/docs/10.1.x/HTML/Content/Authoring/Security/TLS/ImportingANewCertificateToMC.htm

But I'm confused because I added the certificate and restart the console and get the error: ERR_SSL_PROTOCOL_ERROR

So I've to restore keystore.jks several times with no luck.

Please any ideas?

Best regards

Frank
