Update: I confirmed that my APN provider is through "openssl s_client -connect api.sandbox.push.apple.com:443". Unfortunately, the Device Token Validator tool is saying my push token is invalid, and I cannot send a notification through the Push Notifications solution in the developer. It does say that I successfully send a notification on the 7th, but I cannot see to what device.
