I have a Flow which is working fine in all respects, except it is supposed to push a HTTP request to an internal API of ours. This fails with the below message:
"BadRequest. Http request failed with status code 'ConnectFailure' and status message: 'Unable to connect to the remote server'."
My flow is in Europe, so I have allowed the below IPs access to the API (as per https://docs.microsoft.com/en-us/flow/limits-and-config😞
13.69.227.208 - 13.69.227.223, 52.178.150.68, 13.69.64.208 - 13.69.64.223, 52.174.88.118, 52.166.241.149, 52.166.244.232, 52.166.245.173, 52.166.243.169, 52.178.37.42, 40.69.45.126, 40.69.45.11, 40.69.45.93, 40.69.42.254, 52.164.249.26, 137.117.161.181
Following on from the vague error message, what sort of trouble-shooting steps can I do next? Is there any way to run a traceroute from within Flow?
You could try to use other tools(Postman etc.) to test whether you can push a HTTP request to an internal AP.
Check if the network is restricted. The company's network policy may restrict access to some IP, whether you need to install a VPN or create a virtual network.
Also check if the server is working properly, although the possibility is small.
MS Flow don't currently publish FQDNs available for flow scenarios.
Protocols needs to be https.
