  • The error message Volo.Authorization:010001 ("Authorization failed! Given policy has not granted.") typically means the current user or token does not have the required permissions for the API endpoint being accessed.

  • If your refresh token is expiring or being revoked, and tokens are cleared every time you request an API, this is often related to authentication or cookie/session issues, especially in browser-based applications.

  • Common causes and solutions:

    1. Token/Permission Issues: Ensure the user has the correct permissions and roles assigned for the API endpoint.
    2. Token Storage: Make sure your access and refresh tokens are stored securely and persistently (e.g., localStorage, sessionStorage, or cookies) and are not being cleared unintentionally (such as on page reload or navigation).
    3. SameSite Cookie Policy: Modern browsers enforce stricter cookie policies. If you are using cookies for authentication, you may need to adjust the SameSite attribute. See the official ABP article for handling SameSite cookie issues, especially for Chrome and Safari:
       • Patch for Chrome Login Issue (IdentityServer4 SameSite Cookie Problem)
    4. Token Expiry: If your refresh token is expiring too quickly, check your IdentityServer or OpenIddict configuration for token lifetimes and adjust as needed.

  • Steps to resolve:

    • Verify user permissions and API policies.
    • Check how tokens are stored and ensure they persist across navigation.
    • Review and update your authentication cookie settings for compatibility with all browsers.
    • Adjust token lifetimes if necessary.

  hi

  Can you share the full debug logs (logs.txt) of all your projects?

  https://abp.io/support/questions/8622/How-to-enable-Debug-logs-for-troubleshoot-problems

  You can delete the logs.txt and reproduce the problem, then share it with liming.ma@volosoft.com

  
  var loggerConfiguration = new LoggerConfiguration()
      .MinimumLevel.Debug()
      .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
      .Enrich.FromLogContext()
      .WriteTo.Async(c => c.File("Logs/logs.txt"))
      
  
  IdentityModelEventSource.ShowPII = true;
  
  IdentityModelEventSource.Logger.LogLevel = EventLevel.Verbose;
  var wilsonTextLogger = new TextWriterEventListener("Logs/identitymodel.txt");
  wilsonTextLogger.EnableEvents(IdentityModelEventSource.Logger, EventLevel.Verbose);
  

  Thanks
