This occurs when either being in the wrong mode (sandbox vs. production) or having a mixture of sandbox and production in your arguments to curl. It is most likely not the curl issue that existed a few years ago.

When you generate your certificate, generate both certificates - Sandbox and Sandbox + Production. Apple will generate the 'sandbox' as 'development', which those two terms are used interchangeably - and you might think that because you aren't in a sandbox, that you are by default in production path that includes development.

Create two curl commands, one for sandbox and one for production. Besides the certificate, you need to change the http reference in sandbox to "https://api.sandbox.push.apple.com".

What is most likely happening above is that you generated the app from xcode (sandbox/development) and instead you are using the http reference for testflight (production), so it's giving you the ambiguous error for what is most likely a specific issue.

The api references change, so check the latest on the apple api. Think in terms of where your build came from - xcode or testflight/app store, and then that would determine if you use sandbox or production.

I understand that you are trying to test the push notification by using your .pem file. Please try the following steps.

Instead of giving the certificate path, change the directory of the terminal to the folder which your .pem file contains.

then, run the following command,

For Development APNS:

curl -d '{"aps":{"alert":"hi","sound":"default"}}' --cert yourpem.pem: -H "apns-topic: yourbundleID" --http2 https://api.development.push.apple.com/3/device/yourdevicetoken

For Production APNS:

curl -d '{"aps":{"alert":"hi","sound":"default"}}' --cert yourpem.pem: -H "apns-topic: yourbundleID" --http2 https://api.push.apple.com/3/device/yourdevicetoken
