Connect REST HTTPS Error

Hi,
I am currently experiencing issues when trying to create an HTTP REST rule in Pega. Everytime I try to access an HTTPS URL, the connection fails with this error:
** ** Caught unhandled exception: java.net.UnknownHostException: pdn.pega.com: unknown error
I am able to connect to a normal HTTP URL e.g. http://pdn.pega.com but no HTTPS connections are possible.
Are there any certificates that I need to install or any other changes to Pega I need to make?
Thanks,
Jack

The error "java.net.UnknownHostException: " suggests that the PRPC host is unable to resolve the hostname "pdn.pega.com" - rather than it being an issue with specific protocols (but I could be wrong - I am unable to explain why your CONNECT-HTTP rule is able to reach 'http://pdn.pega.com' ?)


From the PRPC Server's host Operating System : can you run:



nslookup pdn.pega.com


And confirm that you get a DNS Record Response (as opposed to a '** server can't find xxx' type message).

Hi Jack,


Are you using any security settings for connect-REST, if not please try to get it from REST service and install it. And use authentication to access Connect-REST.

I'm not sure what you mean by security settings. Is this something done in Pega or on the server side?

Hi Jack,


Like John said, issue could not be specific to the type of protocols being used as secured/unsecured since if there is an issue with HTTP/HTTPS then the error should've come related to SSL something as 'peer not authenticated' etc.


Have you tried using IP address instead of domain name and try to connect to service?


Thanks,

Hi Habeeb


I have tried what you suggested but unfortunately that's not working either... Have you ever had this problem when trying to pass data through a proxy?


Thanks,

Jack

Hi Jack,


Did you got the resolution on this. As I am also having similar issue with HTTPS URL with REST using POST method.


Thanks,

Hi VaibhavG


I did, the problem was in our version of Pega itself (7.1.8), there was a problem with the REST connection that had been patched in 7.1.9 so a Pega support representative asked the engineering team to create a hotfix which was applied to our system which fixed the problem. I would suggest raising a formal SR with the information I have just mentioned so they can examine your logs and potentially create a patch for your platform also.


Let me know if you need any more help!

Thanks Jack. We got the issues resolved by pega folks.. They had an issue with Maintain session while doing https connection. It was actually creating new client each time even if maintain session on was on. We got the hotfix and is working as expected..


Thanks much for the response !
