HTTP request ERROR FlightXML2


Hello, I’m trying to perform a first test with the example code I found on the web

(https://flightaware.com/commercial/flightxml/documentation2.rvt)(Visual Studio)

I have the code exactly the same as in the example if I have performed all the steps described in the example, but when performing the test I get the following error.

“An error occurred while making the HTTP request to https://flightxml.flightaware.com/soap/FlightXML3/op. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.”

What is the reason for this error? and how do I solve it?

Thanks for all :slight_smile:


This is normally the result of an older .NET install not properly negotiation the correct TLS version. More information can be seen here:
