Error: Socket unusable after connection. Hint: You may be using a certificate for the wrong environment

I am getting this error while sending push notifications using apn for few days. Earlier it was working fine. What can be the root cause for this?

Any help would be highly appreciated.

• do you use the certificate that goes with your build? (Eg if you test with an ad hoc build, you should use that certificate). I find it easier to use the provider authentication tokens
