REST API failure with error java.net.ConnectException: Connection refused (Connection refused)

[Smith Johnson]

Hello,

I have the following REST call to localhost, but I receive the following error. 

If I do this call from Postman, everything works as expected.

Any ideas on how to handle this?

Hello @Smith Johnson ,

Localhost is local to your machine/network and not publicly available to cloud platforms like ServiceNow.

What you need to do is setup a MID server on that machine, and then set the MID Server in your REST call.

Please mark as correct.

Hi, do you send outbound REST message through a MID server? Is web service running on MID server as well?

Did you do a firewall check from you localhost to servicenow?

There may be a firewall block and you may need to use a midserver in your rest api to make it work.
