In a .Net environment, the following code eliminates the error. ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
I am experiencing the same problem. What worked?
Pls. let me know how it was fixed? I am experiencing the same problem.
I am experiencing the same problem. I have successful attempts in SOAP UI but unsuccessful attempts in c# environment. Are you suggesting that the fix is in the openSSL statement that you provided?
I had the same issue using c# (4.5.2). Just add the following lines before you send the request:
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
request.ProtocolVersion = HttpVersion.Version10;
Hi, in my case. Go to propierties of project and update the target Framework from 4.5.2 to 4.6.1 and voilà!
