Hi All,

I am getting below exception when trying to access REST API using API Cloud Gateway.

“Exception”: “API Gateway encountered an error. Error Message: Downtime exception: Connection refused (Connection refused). Request Details: Service - catalogue, Operation - /catalogue/{bookId}, Invocation Time:10:03:27 AM, Date:Oct 3, 2018, Client IP - 203.191.35.25, User - Default and Application:null”

},

What could be the reason?

Please help.

Either the native service might be down or not reachable from API Gateway.

I also suspect connectivity issue between API Gateway (Cloud) and Local IS (running on my laptop) but don’t know the way to check connectivity from API Gateway to local IS.

Is there any configuration that I am misising, either on API Gateway or IS?

Any lead to resolve the issue will be much appreciated.

Hi,

Did you check the firewall configurations? Also try invoking the API directly (not from API Gateway) from the same machine where you have installed the Gateway to check the connectivity

Gateway(Cloud) will not be able to connect to your local server. Cloud can only connect to public interfaces that are openly available.

There are some options like setting up site2site VPN to have the cloud talk to on-prem for enterprise customers.

For trial usages we dont enable those.

Did you check if the native endpoint is accessible from your Gateway container?

Yes,native endpoint is accessible.
