I use FCM in china with proxy；but I met an error that I have no idea about it，I would be very grateful to anyone who can help me point out the problem.

It's likely there is some proxy configuration issue that blocks the POST request to the token endpoint. Could you share more details on how you set up your proxy, and some code to show how you use this library?
