ios universal links - App Search API Validation Tool displays "example.com is returning 469. Please check your url and try again."

Question

I am online a fresh webpage for the purpose of universal links. I put the file in .well-known folder.

In the server log I can see that Applebot got 200 on "GET /.well-known/apple-app-site-association HTTP/1.1"

The only error displayed in the App Search API Validation Tool is: "example.com is returning 469. Please check your url and try again."

I used another tool to check it - branch.io AASA Validator and it displays no errors.

Answer 1

Also make sure you don't have any robots.txt file in the root that disables Applebot

Robots.txt: allow only major SE
