Do you have any guide/tutorial on setting up or bypassing firewalls for microgateways in a private cloud environment?
What are you trying to do?
Trying to reach out an internal service and receiving service unavailable error(code 503). On Trace it indicates an issue with Northbound connection.
First, make an obvious test , try to login to the server hosting the microgateway and make a curl request to the same service.
You need to request your Network Team to trace the request the request at a TCP level and see who is dropping the packet. If it is s indeed a firewall issue, they will need to open the firewall port for the source-destination combination. It's not a problem you can solve as a developer.
