URLError at /admin/push_notifications/gcmdevice/

[jondanao]

Sending push notification to iOS has been successful. But I get this error when sending test message to Android.

The error seems to be happening in gcm.py.

settings.py

PUSH_NOTIFICATIONS_SETTINGS = {
    'FCM_API_KEY': os.environ['FCM_API_KEY'],
    'FCM_POST_URL': os.environ['FCM_POST_URL'],
    'FCM_ERROR_TIMEOUT': 2419200,

    'APNS_CERTIFICATE': os.environ['APNS_CERTIFICATE'],
    'APNS_TOPIC': os.environ['APNS_TOPIC'],
}

Error

Did I miss anything in the setup? Thanks!

@jondanao What is FCM_POST_URL set to?

hi @jamaalscarlett https://fcm.googleapis.com/fcm/send

I created a new django project, installed this package and did all the same setup as the project mentioned here. It worked.

So I uninstalled and installed again this package to the existing project. But error still persists. I'm lost. I can't pinpoint if it clashes with other installed packages. Here's my requirements.txt:

"No route to host" That sounds like a networking issue. Can you ping the fcm endpoint from the server? Does a curl command from the server work?

[jondanao]

@jamaalscarlett : sure is a networking issue. On my local machine, I get this error, but when I execute this on AWS, it does work just fine. Can't really figure out what's causing the error.

This error has nothing to do with this library.
