I’m in the process of developing a web app using an ASP.NET Core Web API (in a Docker container) and a separate Blazor web app. I’ve added individual user account functionality for authorization/authentication using Jwt Bearer tokens. Using the API’s auth endpoints in Swagger works as expected. However, when trying to call the API with POST or PUT requests in the Blazor web app, an error is thrown by both the API and the app. GET requests are working correctly and return data.
