Fix 4: Free up Disk Space with MiniTool Partition Wizard.Var result = await httpClient.GetAsync(url) ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 HttpClient httpClient = new HttpClient() Call asynchronous network methods in a try/catch block to handle exceptions. Test app source if that helps at all: static async Task test(string url)

I don't know if I need to update the certificate store (if that is possible), or if there is a setting I'm missing. I have hit another REST Api that we use that also use Lets Encrypt and that is working.

Our Auth server uses Lets Encrypts certificates and uses OAth and only accepts tls2.1. I have used my little test app as well to connect to other https sites like google and my other rest service and no error is reported on this machine. I tried all kinds of different variations as well such as only tls1.2. += (sender, cert, chain, sslPolicyErrors) => true ServicePointManager.Expect100Continue = true Some of the code changes I made below: = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12 I have modified my app with quite a few changes I have found by searching all with the same results as well. I used IISCrypto to change and configure all manner of settings and testing in between. There are a lot of these errors in event viewer, I just copied three of them in case they are actually relevant. The Windows SChannel error state is 1205.Ī fatal error occurred while creating an SSL client credential. The TLS protocol defined fatal error code is 40. This may result in termination of the connection. The TLS protocol defined fatal alert code is 40.Ī fatal alert was generated and sent to the remote endpoint. Please contact your site administrator.Įrrors From Event Viewer: A fatal alert was received from the remote endpoint. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. This is the same no matter what settings I change on the server or in the app.Įrror from my app: AuthResponse is null: FalseĪuthResponse ErrorException: : The request was aborted: Could not create SSL/TLS secure channel.Īt (TransportContext& context)Īt ()Īt (HttpWebRequest webRequest)Īt (String method)Īt (String httpMethod)Īt (IHttp http, String method)Īt (IRestRequest request, String httpMethod, Func`3 getResponse)ĪuthResponse ErrorMessage: The request was aborted: Could not create SSL/TLS secure channel.Įrror from IE11: Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to again. I have no idea what changed the last couple of days unfortunately.

This app have been working up to about 2 days ago on this machine according to my client and uses. But does not establish a connection on my clients Windows Server 2012 hosted by his ISP. I have a peculiar problem where a c# app works on all other machines and other client machines I have tested.
