Hi
Getting the UnknownHostException in logs during external web service call.

Hi,
Is the host mentioned in the exception "gxdfg.abc.com" reachable from the system where prpc is running ? I mean able to ping or access the rest service out of prpc ?
I couldn't mentioned exact service host name over here due to security issue,so updated the some absurd host name .
However ,service host is reachable from pega PRPC as able to ping the host name.
The host name can be accessed while in client network .

Hi Brahma,
Can you please use IP address instead of domain name?
Also, as mentioned by Jeff, it is really required to have PRPC version for better advice. Therefore, we suggest you to provide PRPC version every time you seek help.

are there any proxy servers involved in your setup? If the external web service is hosted in the internet, normally company IT will require the request going through proxy server.

Hi,
Answering these questions will improve the answers you get on this forum:
- What version of Pega is in use?
- What application server are you using?
- What version of Java is in use?
- Is it possible that the Pega server is trying to complete the connection using ipv6?
Aditya,
Today ,one of the agent interval has been traced in prod,and i didn't see any issue with web service call as it returned valid response as expected.
Seems to be an intermittent issue ,as agent makes the web service calls for every 30 sec,but count of the exception being occurred in logs is very minimal(6-7) per day.
we are still thinking of what could be the issue for causing the exception.

this proves that this has to do with the running state (not configuration per se) of the system. Perhaps, DNS server/networking issues?

As kevin said, if a proxy or load balanced configuration involved in the setup, then the network blips could be the reason for intermittent failures.
