Note that same code always works on my development machine, on two other machines i also got access token but always fail on upload.

Hi @iz111

When you get an access token, it is actually an object that contains JSON key-value pairs, and you only need to pass the Token value. So please change your code to:

requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accesstoken.Token);

Hope this helps.

Hello iz111,

Thanks for reaching out!

This error message "CompactToken parsing failed with error code: 80049217" generally occurs when the token used is invalid.

I don't understand, it is working on my development machine. I received the token.
If token is invalid it might be something wrong with permissions or the way I ask for token?
Following are permissions on the Azure for my app:

Code to receive access token:

publicClientApp = PublicClientApplicationBuilder.Create(ApplicationID)
                                                                  .WithAuthority(AzureCloudInstance.AzurePublic, "common")
                                                                  .WithDefaultRedirectUri()
                                                                  .Build();   

authResult = publicClientApp.AcquireTokenInteractive(scopes)
                                                .WithAccount(accounts.FirstOrDefault())
                                                .WithPrompt(Microsoft.Identity.Client.Prompt.SelectAccount)
                                                .ExecuteAsync().GetAwaiter().GetResult();

When I do upload I pass token as follows:

requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", <accesstoken>);
requestMessage.Version = new Version(1, 1);
