CrateDB cannot connect in HttpEndpoint to remote secure server - cratedb

Question

I've been testing crateDB 3.3.4 for a few weeks now, and I've always been connecting through localhost (127.0.0.1) in http. I've been bulk importing data with HttpEndpoint on my localhost successfully.
I'm now testing on a cloud cluster in https. I manage to open Chrome and logon on the server, but I cannot manage to remote in C# via HttpEndpoint.
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://remoteServerUrl:4200/_sql");
httpWebRequest.Method = "POST";
httpWebRequest.Credentials = new NetworkCredential("username", "password");
httpWebRequest.Timeout = 600000;
httpWebRequest.ContentType = "application/json";
using(var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
streamWriter.Write(request);
streamWriter.Flush();
}
HttpWebResponse response = (HttpWebResponse)httpWebRequest.GetResponse();
success = response.StatusCode == HttpStatusCode.OK;
When I try the following code, I always get "The underlying connection was closed: An unexpected error occurred on a send." and in the exception, I see "Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host."
Any Idea what I'm doing wrong here? I was doing the same thing before, on my localhost, but without specifying credentials, and it was working great.

Answer 1

Assuming from your code sample you are using password authentication. Permanent solution would indeed be using autorization header.
As described here https://crate.io/docs/crate/reference/en/latest/admin/auth/methods.html#password-authentication-method

Answer 2

It's not a permanent solution but for test purposes it works. I worked around the problem by adding the Authorization Header directly in my httpwebRequest.
httpWebRequest.Headers.Add(HttpRequestHeader.Authorization, "SomeBasicauthenticationToken");
To find the authentication token to pass, simply put the username and password in a basic authentication token generator like this one :

But if anyone has a permanent solution, I would still like to see what it is.
