While configuring certificate for Push Notification on my ios build of cordova project using OneSignal, the certificate is getting rejected every time I'm trying to configure it.
I've followed steps mentioned in https://documentation.onesignal.com/docs/generate-an-ios-push-certificate
I've tried using OneSignal Provisionator Tool, and generated certificate using KeyChain access as well without any result.
You can test APNS connection with this script:

This script requires your key and certificate in pem format. To convert from p12 use
openssl pkcs12 -in PushCertKey.p12 -out PushCertKeyNoCrypt.pem -nodes
OneSignal had a service issue that caused certificates to be incorrectly detected as invalid. It is now fixed, as noted in this status update.
