What should I do if I encounter a JWT authorization failure in ASP.NET Core?

First, check if the JWT token is valid and not expired. You can use tools like jwt.io to decode it.

How can I verify if the token is expired?

Look for the 'exp' claim in the token payload. It indicates the expiration time in Unix timestamp format.

What if the token is valid but I'm still getting an authorization error?

Ensure that the token is being sent in the Authorization header as 'Bearer {token}'. Also, check your authentication middleware configuration.

Can I see an example of how to configure JWT authentication in ASP.NET Core?

Sure! You can configure it in the Startup.cs file using services.AddAuthentication() and services.AddAuthorization() methods.
