Connection refused on example code about firebase-arduino-wifi101 HOT 12 CLOSED

Never mind! My firmware was outdated. After trying for over 2h I just found out....
If anyone has the same issue: https://www.arduino.cc/en/Tutorial/FirmwareUpdater

Maybe it's a good idea to mention this either in the error message or here in the docs :)

Click add domain button and add your project host myproject-default-rtdb.europe-west1.firebasedatabase.app

Ok thanks

Hi! I'm experiencing the same issue on the example code (connection refused). The firmware is updated to version 19.6.1 and the MKR1000 does connect to WiFi (it shows connected with IP...). I changed the database secret a couple of times still the same problem though.

The library was test with my MKR1000 before I post this comment which it works normally without the problem.

Please try to upload certificate and also add the domain of your Firebase host.

from firebase-arduino-wifi101.

The Firebase host that I have is myproject-default-rtdb.europe-west1.firebasedatabase.app and for the certificate I am not sure which one to upload. Is it the authDomain?

from firebase-arduino-wifi101.

Uploaded the certificate but still get a connection refused.

No internet connectivity, check your router or WiFi hotspot.

Make sure access point is for 2.4G WiFi instead of 5G.

I'm using a mobile hotspot, it says the broadcast channel uses 2.4GHz and the MKR1000 appears as connected devices.

Let try to update the WiFi101 library.

You must provide the valid host in FIREBASE_HOST e.g. myproject-default-rtdb.europe-west1.firebasedatabase.app without schemes (https://) and backslash at the end.

For FIREBASE_AUTH, try to renew your database secret from Firebase project console.

If you're still cannot connect, the issue is on your device hardware.

Try to change the shorter USB cable to provide more stable power.

Must be a hardware issue then, thanks for the help!
