after some work i got my first iPhone registered at mdm 😄
But it only connects once and i get the error "APNS service certificate validation failed"
I allready checked kb for mdm troubleshooting and investigated root certs:
grep Entrust /etc/pki/tls/certs/ca-bundle.crt
# Entrust Root Certification Authority
# Entrust Root Certification Authority - G3
# Entrust.net Certification Authority (2048)
# Entrust Root Certification Authority - EC1
# Entrust Root Certification Authority - G2
i tried openssl:
openssl s_client -connect gateway.push.apple.com:2195
SSL handshake has read 4066 bytes and written 338 bytes

i'm after this for a few hours now - maybe someone has some ideas for me?
i was thinking about my firewall but no outgoing traffic is blocked at all.
Thanks in advance!
