The issue ended up being related to the export of the p12.

When exporting the p12 we multi selected to export public and private to generate the p12. When only exporting the public, the size of the p12 was 3217 bytes. The 3217 byte file worked.

If your p12 is 6140 bytes you'll need to regenerate it. I resolved this issue by regenerating the certificate. For more information take a look at this.

You only use certificate in .p12 format to encode your message, then APN will identify who you are before accepting the push since the certificate was issued by them. With "multi selected export", you are including both cert/publich key and private key content and normally, the BEGIN PRIVATE RSA KEY is placed first. Then you will not be able to send. Br,
