Error pushing data to Firestore

First of all thank you for the awesome library . I am using the updateDocument.ino sketch , with UserAuth , but I am getting this errror continuously.
msg: Terminating the server connection... Error task: task_96060, msg: HTTP Status 403, code: 403 Event task: task_102003, msg: authenticating, code: 7 Debug task: task_102003, msg: Connecting to server... Event task: task_102003, msg: auth request sent, code: 8 Event task: task_102003, msg: error, code: 11
Can you please guide me towards the issue .
Thank you

The SSL client e.g. WiFiClientSecure is on your side.

You have to debug it yourself why it cannot access to Googe API server.

The possible reason is your network Firewall blocking.

Please reset your router or change the network.

Another cause is your device and code.

If your board crashed and reboot repeatedly and your device is trying to connect to server repeatedly then crash. The DDoS prevention of server may block your server access, please remove the code that connected to WiFi and debug your code to fix the crash and resume the WiFi connection.

In case of device crashed due to memory issue in ESP8266, please select the proper Heap by follow this documentation.

Like in your examples you are using UserAuth for authentication , can we use ServiceAuth or other type of auths as well correct ?.
I dont think so it is a wifi related problem as many of my friends are also getting the same error with their wifi . Maybe its the code thats causing it , anyway I will have to do step by step to check what part is causing the error .
Also i tried creating a new firebase project and used its api key and user's email and password (email/password authentication) still i got the same error .
Thanks , if there is anything more you could point to me at ? Could esp's time be an issue , maybe difference in esp time and the google api server's time ?

As I told you, WiFiClientSecure was defined on the user code side.

It performs the networking work, and it used to connect to googleapis.com via port 443. The http code 403 forbidden SHALL not return by googleapis. It returns from some middleware not a real googleapis.com server.

To connect to internet without Firewall and proxy server, you should use your mobile hotspot as AP.

You should create your own simple code to test the internet access by using WiFiClientSecure to connect to the secure server e.g. google.com or github.com via port 443.

The Firebase authentication and server time are not involved because we are talking about the googleapis server request for token exchanging.

Did your country was blocked by Google?

I never face this problem in all my corporate, mobile and home Fiber networks from my internet service provider in my country.

No , the country is not blocked by Google Apis , I am in India .
About the WifiClientSecure , let me try and run a simple sketch to test the internet access like you told.
