Firestore offline error even after trying everything

I've been stuck on this for days. My Firestore database is reporting "offline" in my app, even though:

· The REST API works (I get a 200 response)
· Firestore API is enabled
· Security rules are public
· API key has no restrictions
· I added experimentalForceLongPolling: true
· Internet is fine (tested on different networks)

Yet my app still says: "Failed to get document because the client is offline"

Has anyone solved this? What am I missing?
