<br>
What could be the root cause for this error in Aerogear UPS: Error sending<br>
payload to APNs server: javax.net.ssl.SSLException: Received fatal alert:<br>
internal_error ?<br>
<br>
Certs were managed by another group in the company. How can I prove to them<br>
that this is a certificate issue (not generated in Apple for push<br>
correctly)? It failed when Apple does not like this .p12 cert. (it's freshly<br>
generated so it should not expire)<br>
<br>
TIA.<br>
