We have our own developed software which we can use to connect to webservices. We now did some changes in order to call endpoints that only accept TLS 1.2 requests. In a small testsetting we see that we can connect a TLS 1.2 endpoint. But in a sample website project we still get errors while doing requests to a TLS 1.2. Given the fact that the small (non-website) testsetting is succesful, we think it has to do with the configuration (for example in the web.config of our website project) I have the next questions:
- how can I see which protocol is used when doing requests to an endpoint? What tools can I use to see this exact call (in order to be sure that I don't do a TLS 1.2 call);
- our software is developed using .NET 4.6.2. This is the framework to use to do TLS 1.2 calls. Maybe the calls are done not using this version, but an older version. Can I force webservice requests using this framework?
- is there a setting (for example in web.config) which I can use to force my requests to be TLS 1.2?
