Rest Message HTTP Status 0 in ServiceNow, but is working fine in POSTMAN

[Tadz]

Hi Everyone,

What could be the cause if rest message is returning https status 0 in ServiceNow. But is working fine in postman.

This was working before in ServiceNow. No changes in rest message configuration.

I'm thinking it has something to do with Instance slowness or firewall.

Hi if the REST call works in postman but not in your SN instance then your endpoint may be behind a firewall. Have you configured a MID server for your REST call from SN?

Hi David, how do we check if there is a midserver used?

[DScroggins]

The MID server would be configured in your outbound REST message HTTP Method. You can check there if you have a MID server selected. See the docs for additional info: https://docs.servicenow.com/bundle/newyork-application-development/page/integrate/outbound-rest/concept/c_OutboundRESTMIDServerSupport.html Hope this helps.

Hi ,

Check the firewall setup for your endpoint to which your trying to connect. if yes Kindly use MID Server.

Thanks,
