There was an error authenticating the sender account

Hi
I used the library as is on my localhost and was able to send the message successfully.
But trying to use it on my server, I get the error -
There was an error authenticating the sender account

This is however the same file that I used on my local. Upon closer look, I found that the php curl is changing the content type that was set from application/json to text/html and that is what is causing the error.
Any idea why curl is changing the content type?

Hi @arunondeck

Unfortunately no guess for now. I didn't faced this issue ever before.

Google changes things around. Library needs fixes or upgrades to FCM
