when I tested host (sumxg594-del4) from command prompt, it is responding, but when I try same host along with port ( sumxg594-del4:99 )from http client service, I am getting above error.

my url got GET webservice like : http://sumxg594-del4:99/sites/KLMpcIntegration/_api/web/lists(guid’cb0145c5-4581-4d56-a8b6-8ada8a29ec7a’)

Thanks,

As a security concern, do not post client hostnames or IP on the forums.

There are several reasons for this error, did you check to replace the hostname with ip address (try nslookup HOSTNAME).

Check DNS/server configuration and make sure there is no network glitch (firewall block) involve network team if there is some. Hope, you have tried a telnet or ping from the IS machine.

Try doing a test from Postman or Soap UI and see the results.

Hi Mahesh,

Thanks for your suggestion, but whatever I have provided Host and port number are manipulated, that is reference values.

Thanks,

That’s perfect. Any clues on your issue?
