title: Network request started failing in production app with No valid NAT64 prefix error over WIFI but works on mobile data, Android only
body: <p>We started getting a <code>Network Request Failed</code> error in our production app when users try to login on WiFi, mobile data never has this issue. It occurs on most but not all WiFi networks. We have pushed no changes to our app recently and it only occurs on Android. Pertinent logcat message is <code>No valid NAT64 prefix</code>. Any ideas what could happening? </p>
