issues with Arduino MKR Wifi 1010 board connecting to Firebase RealTimeDatabase

[GarethLHS]

I complete the pre requisites. Firebase console create real-time database create copy API create Auth user and allow anonymous.
I open the Arduino development environment use the example from File --> FirebaseClient --> RealTimeDatabase --> Async --> Get
Firebase version I'm using 1.1.5 I update; WIFI_SSID,WIFI_PASSWORD,API_KEY,USER_EMAIL,USER_PASSWORD, DATABASE_URL
I'm just requesting Database.get(aClient, "/test", asyncCB); I've commented out the other get requests. In my Firebase real time database I have /test setup with 1 as a value.

Anyone else having any issues with the Arduino MKR WiFi 1010 board?

I set my database rules as

".write": "auth != null"
}
}

You have to update your Firebase host certificate in your board.

Add your host database host e.g. xxxxxxxx.firebasedatabase.app by follow the steps in the link below.

Hello @GarethLHS and @mobizt ,
I am using Uno Wifi R4 with Arduino IDE, and I am facing the same issue.

I tried adding <project-id>.firebasedatabase.app but it says unable to upload. So I tried uploading authdomain i.e. <project-id>.firebaseapp.com. It gets uploaded but issue stays as it is.

I am not totally clear what URL to put to fetch SSL certificate.

Also I observed whenever my certificate is uploaded successfully my arduino disconnects from IDE on its own, if that is indication to any other issue.

@UvrajSB

You can update firmware and add the SSL certificate again.

I updated the firmware successfully and uploaded arduino.cc:443 and <project-id>.firebaseapp.com:443 as certificates successfully. Still the issue persists. Kindly help

[mobizt]

If you run the pure library example code without third-party library and still get the problem.

Then check your internet, network, AP and router.

The WiFiSSLClient cannot connect to the internet is all I know.

Resolved!
Actually the issue was that in my Firebase project I had only enabled Firebase realtime database but not Authentication as I was only interested in Firebase realtime database. Once I enabled the Authentication and added my email and pswd it started working.

I was in the assumption that the email id and password asked were only related to my firebase signing.

Thank you for the prompt response @mobizt and helping me.

If you have the problems, please read the documentation first which it is better than guessing.
