I am developing a Word VSTO add-in so that I can call a Cognitive Services knowledgebase service. The code is pretty straight-forward and works fine when I run it from a windows console app (a similar call in python also works without issue):
Debug.WriteLine("beginning of the try");
string azureEndpoint = "https://redacted.cognitiveservices.azure.com/"; // Replace with your actual endpoint URL
string subscriptionKey = "redacted"; // Replace with your actual subscription key
Uri endpoint = new Uri(azureEndpoint);
AzureKeyCredential credential = new AzureKeyCredential(subscriptionKey);
QuestionAnsweringClient client = new QuestionAnsweringClient(endpoint, credential);
string projectName = "redacted";
string deploymentName = "production";
QuestionAnsweringProject project = new QuestionAnsweringProject(projectName, deploymentName);

@AdamMorgan-1941 AFAIK i think 10054 indicates the connection was closed. I do not have experience with word add-ins but are there any guidelines or documentation on how to call an external endpoint? I think the connection could have been closed if the SSL cert is not valid or trusted. Is it possible to check using any developer mode for more details? See this thread for some suggestions.
@Rohit Mungi , thanks so much for the response! I am actually calling an Azure language service endpoint, so I don't think the issue is with a cert. Also, the same exact code works fine when run as a console app on the same computer (and the same endpoint also works when called from python). But I think the answer is somewhere in this area. I've seen other people having the same error when calling other azure endpoints - in those instances the issue was tls not being set to 1.2. I don't see that option in the azure language service.
@AdamMorgan-1941 If the endpoint works from other sources the same applies in this case too but I am not sure what is the cause of this error when calling from this environment, you will have to pass the request details to the service team to understand why this error code was passed while calling from this environment.
Thank you @Rohit Mungi . How do I go about doing that?
I gave up on this approach and instead used office.js. I had no problems calling the services from there.
