iOS Push broken after upgrade to 2.2.6

After upgrade parse-server from 2.2.2 to 2.2.6, APNS broken. I couldn't send a notification to iOS anymore. In log, it shows:

ERR!
parse-server-push-adapter APNS
cannot find vaild connection for XXXXXXXXXXXXXXX

Update 1: Rollback to @2.2.5 error still happened. But sometimes Android worked, sometimes didn't. Sometimes iOS worked, sometimes not.... This time, APNS is silent failed, GCM failed with error code 401. Will change version to 2.2.4 and let you guys know soon.

The problem seems to be in APNS key, will re-open if found any issues.
