When app installed from app store, iOS requests apple-app-site-association file for very first time, as I know.

But if the server was down at that time, iOS will fail to obtain apple-app-site-association file.

My question is, when iOS will retry to download that file under that situation.

I confirmed that, 1) When App Installed or 2) When device reboot

iOS requests apple-app-site-association file, but I expect that more circumstances exsists.

Is there anyone who knows?

The reference describes that situation.

A number of issues might cause the validation to fail.

The JSON signature is invalid. The association is denied.
JSON file is invalid or does not contain the application identifier. The association is denied.
The server returns a 300-499 code. This includes redirects. The association is denied.
The server returns a 500-599 code. The system assumes that the file is temporarily unavailable and tries again. By default, the system tries every 3 hours for up to eight tries. It also tries whenever the app calls the
```
SecAddSharedWebCredential
```
or
```
SecRequestSharedWebCredential
```
method.
