Unable to connect to openhab cloud using https configuration at openhab connector

When I configure openhab paperui using url http://13.XXX.XXX.XXX:3000 I am able to connect to the openhab cloud connector.

But when I am trying to configure it with the url https://13.XXX.XXX.XXX (or with https://13.XXX.XXX.XXX:3000) I am not able to connect to the cloud instance. I have configured nginx with openssl certificate.

Hi,

what Java version are you running?
Can you connect to the https URL at all with https://your-url-name:443?
HTTPs should be 443 not 3000 in the URL.

Java version that I am using is 1.8.0_161

As you mentioned above I tried connecting to the url https://13.XXX.XXX.XXX:443 and even https://13.XXX.XXX.XXX still I am not able to connect to the cloud instance.

But when I try to configure openHAB paperui http://13.XXX.XXX.XXX:3000 I will be able to connect to cloud instance.

Was able to resolve the issue by creating Lets Encrypt certification.
