expo update url not found

My eas preview build android apk is failing on startup. using android studio logcat, I discovered it was throwing this error: Failed to download remote update from URL: https://u.expo.dev/d7cc05cd-5e81-4274-b39d-947bbe5927fa: Unable to resolve host “u.expo.dev”: No address associated with hostname.

I have searched eas build docs on eas and app.json files configuration and nothing has been helpful so far. Please help

This error means your device cannot resolve u.expo.dev (DNS issue). Typically, devices should not have this issue. However, if your device or network connection is modified to block domains, that could prevent DNS lookups.
