I received an update to the APN root certificate. Testing the connection using MDM.pem to the push environment returned the following error:BadCertificateEnvironment
MDM certificates cannot be used in Sandbox APNs. That's why you are getting this error.
We do have a production endpoint set up for testing the new root cert. You can use:
openssl s_client -connect 17.188.172.30:443 -showcerts
Or use that endpoint to send an actual MDM push for a complete peace of mind.
