VNC server doesn’t have to have certificate

Trying to connect to xxxxx.vmxx.wedos.net:xxxxx (where x numbers associated with my VPS SSD) with ssvnc I get the message „An Error occurred in fetching SSL Certificate from…“

Accessing the same address through a web browser, a SSL certificate is not served.

Executing the command: openssl s_client -connect HOST:PORTNUMBER (where host, portnumber as the associated with my VPS SSD) returns this:

$openssl s_client -connect $HOST:$PORTNUMBER

CONNECTED(00000003)

—

no peer certificate available

I get the feeling that there is no SSL certificate there, can you verify and provide guidance on how I can connect?

Thank you
