Posted on by ShruthiKrishnaswamy95

I am trying to send a GET/POST call to an API with API key authentication. It fails while getting a response with the error "Request was aborted could not create ssl/tls secure channel ". I have tried all the possible changes provided in the blogs like assigning Security protocol type to TLS1.2 to the security point manager, Enabling TLS1.1,1.2 from the settings, adding it to the trusted site, etc.

Any help will be appreciated.

Hi Ergun,

This is what I get when I try from my machine. Also I ran the code that is there in the link you provided, TLS12 is enabled which I have added before the CREATE statement.

System.Net.ServicePointManager::set_Expect100Continue(true);

System.Net.ServicePointManager::set_SecurityProtocol(System.Net.SecurityProtocolType::Tls12);

clrObj = System.Net.WebRequest::Create(url);

Regards,

Shruthi

Nope I didn't mean add ServicePointManager to code. Link have a job which is shown ServicePointManager 's status(value).

What I want learn is server's and local's status (and lastly ServicePointManager a global value(appDomain) don't change it If you not sure)

static void CheckEnviornmentSecurityProtocol(Args _args) { int i; boolean ssl3Enabled,tlsEnabled,tls11Enabled,tls12Enabled; ; i = System.Net.ServicePointManager::get_SecurityProtocol(); ssl3Enabled = i & enum2int(System.Net.SecurityProtocolType::Ssl3); tlsEnabled = i & enum2int(System.Net.SecurityProtocolType::Tls); tls11Enabled = i & enum2int(System.Net.SecurityProtocolType::Tls11); tls12Enabled = i & enum2int(System.Net.SecurityProtocolType::Tls12); info(strFmt("'%1' enabled: '%2'", 'ssl3', ssl3Enabled)); info(strFmt("'%1' enabled: '%2'", 'tls1', tlsEnabled)); info(strFmt("'%1' enabled: '%2'", 'tls11', tls11Enabled)); info(strFmt("'%1' enabled: '%2'", 'tls12', tls12Enabled)); }

Do you have a firewall or did you changed registry. What OP system you have (From explorer image I can see your status is not code related)

No, I did not change registry too. Its a regular 2 tier cloud machine deployed from LCS.

The code can give this error for many different reasons. The first ones that come to my mind are .Net framework, certificate, Ciphers, WebRequest.Timeout = 0 ...

However, you can't even see it from explorer. You have a different problem. You can check out the link below

Nope, I don't think you have a code related problem. Operating system, security, registry etc.

Did you try from a different environment, maybe from local (web browser or Visual studio)
