URL to 3rd party service unavailable through gateway

Issue/Introduction

When try to access a 3rd party URL service in gateway we get a connection reset error.

Error presents itself as follows:

• Unable to obtain HTTP response from https://external.domain.com/path/to/remote/service: Connection reset'.

Environment

Release:
Component: APIGTW

Resolution

This is due to a communication error between the gateway and the 3rd party URL service. 

A "curl -v -k https://external.domain.com/path/to/remote/service" from the gateway will show that we receive errors when trying to communicate to this 3rd party service. 

These errors are network, not gateway related.  They are most likely a firewall issue.  We recommend speaking with your networking team to resolve.
