Logging into C# Dev Kit causes 401 with individual license

[kroppt]

Type: Bug

1. Install C# Dev Kit
2. Open a solution with C# Dev Kit running
3. Log into C# Dev Kit with an individual license
4. See error logged under "C# Dev Kit": IdeBenefitsSource: Failed to fetch entitlements. Error: 'Error: Request to https://api.subscriptions.visualstudio.microsoft.com/Me/Entitlements/IDEBenefits?api-version=2023-03-26&caller=vscode failed with status code: 401 and response ""'
5. The language server does not function

The following did not help:

• Ungrant and regrant account access to C# Dev Kit
• Sign out and sign back in
• Double check I can sign in on visualstudio.microsoft.com
• Uninstall C# Dev Kit and C# extensions and re-install them

Thank you for the suggestion. Yes, I worked with only the C# extension, which does not need login. I disabled C# Dev Kit until this problem is fixed.

[AyrtonAlbuquerque]

I'm also having this problem but on Ubuntu only. In my windows 11 setup it works fine but in the Ubuntu this error occurs.

@AndreyTretyak would you please take a look? Related is #1384

I just tested this with the latest VSCode 1.95.0, C# 2.50.27, and C# Dev Kit 1.11.14.

The error shows up in the C# Dev Kit logs, but the behavior is a bit different. The LSP functionality appears to be working, but it's not clear whether the C# extension is falling back to Omnisharp or sticking with C# Dev Kit (somehow). It seems like it's working with the C# Dev Kit LSP.

If it helps, I noticed the Microsoft Authentication logs show the following:

Even though things are currently "working", I'd rather keep this open until we know it's fixed.

[AndreyTretyak]

We have an ongoing problem with https://api.subscriptions.visualstudio.microsoft.com service accessibility due to increased security requirements, but there is fallback https://app.vssps.visualstudio.com that we are calling for getting license that supposed to work and provider correct license.

So having this error in logs should not be blocking in any way.

Are you seeing incorrect licensing displayed by C# Dev Kit?
Are there any problems caused aside of this message being in the logs?
Even with us failing to obtain license via both sources you should be able to fully use C# Dev Kit without any blockers.

@AndreyTretyak

Are you seeing incorrect licensing displayed by C# Dev Kit?

When I click on the C# button in the bottom right, it says, "This software is licensed to --snip-- under an individual license." That is the correct license.

Are there any problems caused aside of this message being in the logs?

No, not currently.

I don't know why it was failing initially and now functions. I don't know whether there was a bug that got fixed or if it was just "fricked". You may close it if you think that the bug does not exist.

@AyrtonAlbuquerque Are you still getting this issue?

I'm not. everything seems fine now, although i have not changed anything.
