HTTP request to call service but got back request

Hi all,


I have a SAP server and developed an customized API for HTTP request.

However, when I use the "HTTP" to call the API in flow, it return "BadRequest. Http request failed with status code 'ConnectFailure' and status message: 'Unable to connect to the remote server'."


Seem the Power Automate cannot reach the internal server.

After googled, I found the IP of Power Automate:


And I whitelisted all IP in the server, however, it still not work with same result.


1. Any tools can help to troubleshoot/ the API is able to called by Power Automate?

2. Any additional configuration is required?

Hey @Lam01007 


The First step would be to try using a REST client such as postman or ARC. Can you please confirm if that works?
