$ curl -I https://9.185.173.135
curl: (35) Unknown SSL protocol error in connection to 9.185.173.135:443
This is an secured page that I need to access. But I don't know how to obtain its certificate file. I tried to use Firefox, but it says couldn't get any ssl certificate once the url is entered.

The server is definitely reachable from my laptop. Once I get the certificate file, I assume I can then import it to Firefox and then use my credentials to pass the authentication (I already got the username/password).
Sorry I am no expert in security at all. Is there anything else I can try?
Many thanks in advance.
If you see an error like this: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol , it could be due to you typing the hostname incorrectly or the hostname is not yet tabled in your DNS. You can verify that with a simple "host" or "nslookup".
In my case on a AIX VM also this problem, use --cacert
to specific a cacert.pem
curl --cacert /var/ssl/cacert.pem https://localhost:3000
