Hi Hendrik Striepe,

I have tested here locally + on a clean vm installation (plugin version 5.3.12, against Studio version 16.1.4), but unable to reproduce the issue that you have reported here.

Please try the following and reconfirm on your side:

• Test without any other plugins loaded in Studio to exclude any external influences (e.g. unknowns)
• Test against Studio 2021 sr1 cu4?

Dev Notes (for internal reference):
Reviewing the code just now, I have seen that we are referencing RestSharp (RestClient) with this plugin; we will need to plan a development cycle to remove this (for future releases), as we have seen unsupported issues directly related to this assembly in the past; to be substituted with standard http client implementation

Hi Patrick Andrew Hartnett,

we tested again with Studio 16.1.4.4184 and MT enhanced 5.3.12 freshly setup, no other plugins installed. Unfortunately we still get a 

Der Antwortstatuscode gibt keinen Erfolg an: 401 (Access Denied). 

through the UI (of the MT enhanced plugin when configuring it within a project template) and the following logs in the Studio Client. I double checked our Azure MT API key, which works fine when using Postman, see attached image.

Hi Hendrik Striepe & team,

I think you are right on the mark with this... it seems that the provider doesn't cater for authenticating the credentials against a specific region.  I will followup with your suggestions and potentially expose an option where the user can specify the region specific header key

Hi Hendrik Striepe & team,

Note: This should be released within the next week once it passes our internal QA procedures; Paul will followup

All changes included with the latest release:

• Version 5.3.13.3 - supports Studio 2021 SR1

Overview

Until now we have hard-coded the URI that is used to authorize the user given a subscription key.  We have changed this to align with the latest release of the Microsoft Translator API so the correct URI is referenced with the HTTP client.  The URI can be different given the specific region that is associated with the subscription.

Updates

• Introduced a new option that is available from the provider settings enabling the user to specify the subscription region (if required).
• Updated the API Connector service to compile a valid URI, that is used to request the authorization token, given a specific region.
• Updated the providers factory to locate the credential from the credential store if derived from the Automation API

Provider Settings

Code Example: demonstrates how to add the provider from the Project Automation API

var templateReference = new ProjectTemplateReference(projectTemplateFile);
var project = new FileBasedProject(projectInfo, templateReference);

var region = "westeurope";
var uri_scheme = "mtenhancedprovider:///";
var uri_provider = "Microsoft+Translator";
var uri = new Uri($"{uri_scheme}?selectedprovider={uri_provider}&region={region}");
			
var tmConfig = project.GetTranslationProviderConfiguration();
var provider = new TranslationProviderReference(uri, string.Empty, true);
var entry = new TranslationProviderCascadeEntry(provider, false, true, true, 0);
tmConfig.Entries.Add(entry);

project.UpdateTranslationProviderConfiguration(tmConfig);

var apiKey = "<api_key>";
project.Credentials.AddCredential(new Uri(uri_scheme), apiKey);

project.Save();
