Hello,

I'm trying to call API services from AL on Business Cenrtral, when I deploy on OnPremise Docker container works correctely, but when I deploy to SaaS I get the error "Could not create SSL/TLS secure channel". The code is:

var
Client: HttpClient;
Request: HttpRequestMessage;
Content: HttpContent;
Response: HttpResponseMessage;
RequestHeaders: HttpHeaders;
ContentString: Text;
ResponseString: Text;

begin
Clear(Client);

Request.SetRequestUri('https:');
Request.Method := 'GET';

Request.GetHeaders(RequestHeaders);
RequestHeaders.Clear();
RequestHeaders.Add('Authorization', '');

Client.Send(Request, Response);

Response.Content.ReadAs(ResponseString);
Message(Format(Response.HttpStatusCode));
Message(ResponseString);
end;

The message error:

Thanks

Hello Davy,

The problem is on the outside endpoint, it must use cipher suites supported from Business Central. Review this on next link

learn.microsoft.com/.../devenv-supported-cipher-suites

I hope this will help you

Hello,

IF external Endpoint use a SSL Certificate and has activated TSL 1.3 it works. But if TSL active is 1.2 or lower doesn't work.It only happens on SaaS environments, OnPremise doesn't happens.

Thanks
