Apple App Site Association 在 Postman 中工作，但不适用于在线验证器

Question

I'm serving the apple-app-site-association through https://xxxxxx/.well-known/apple-app-site-association

If you open the link in your browser or Postman you'll get the file. If I use external validators like: https://branch.io/resources/aasa-validator/ or https://limitless-sierra-4673.herokuapp.com/ It's not working .

Previously I served the exact same file through an NGINX and the validation was successful . (Currently I serve this file with a .Net Core App and in between is NGINX as reverse proxy)

Answer 1

The problem is, that I'm not giving the intermediate certificate in my webserver/hosting. If I provide the fullchain.pem from LetsEncrypt it's working.
