I have to get a certificate from an external organizations server to connect my soap client to it. Usng the command

openssl s_client -connect https://xyz.com/monitor.html:443

gives me the following error,
getaddrinfo: Servname not supported for ai_socktype

Now :-
1. Is there any other way to get the certificate (Putting the address on the browser does not help)
2. Am I using the connect command wrongly, Is there any other way to use the above command

Thank you for your help.

Do you have to open that specific page?  Presumably the host should serve the same certificate for any connection.

Have you tried
openssl s_client -connect xyz.com:443

Open in new window

The host had issues with its own certificate system. So did all the debugging on our side. I also used curl to test it and found the similar issue. So I would say try a few different ways like I did with

1. Directly php
2. Zend framework
3. OpenSSL
3. Curl

Still do not seem to work then may be its the issue with the client setup.
Thanks expert for the help though
