@DTS Engineer It has been resolved. The status of this domain was updated after I deployed a new build.

The issue has been resolved. I found that when submitting a new build, App Store Connect updates the cached status of the domain. The problem I encountered last time was due to a network fluctuation during my previous build submission, which prevented it from retrieving the AASA status of nfc.ttwifi.net. After submitting a new build, a new cache update was triggered, and this resolved the AASA status issue.
