At my company, a proxy configuration error highlighed something very unusual in the log which we don't really like - namely access to "upload.video.google.com" (see anonymized full log below). Can someone tell my why a Firebase SDK adresses such a... spooky resource and whether video is really uploaded?
The app is a Swift project making use of the pods FirebaseAnalytics, FirebaseCrashlytics and FirebaseRemoteConfig.
The full error log:
