Cordova-plugin-push for iOS failing to send notification

I recently updated my xcode and ios to 11 and 13.2 and the plugin stopped sending notifications from iOS. I’m able to receive the notifications though. Here is the error which the API sends back, I have the correct authkey and the firebase is setup with authentication key.

**{"headers":{"normalizedNames":{},"lazyUpdate":null,"headers":{}},"status":0,"statusText":"Unknown Error","url":null,"ok":false,"name":"HttpErrorResponse","message":"Http failure response for (unknown url): 0 Unknown Error","error":{"isTrusted":true}}**

Need help, urgently. Thanks
