Get a internal error

[andyzhou]

I generate pem file by test_certs tool, and used for my app service.
I get following error when start service:
[error] SSL: cipher: ssl_alert.erl:92:Fatal error: internal error
07:00:30.561 [error] CRASH REPORT Process <0.135.0> with 1 neighbours exited with reason: {tls_alert,"internal error"} in gen_server:init_it/6 line 322

Is my pem file problem or others, can you help me? Thanks.

Hi @andyzhou. Currently we have refactored apns4erl supporting the new APNs API. Maybe you should try it :)
which url are you trying to connect? if you are connecting against api.development.push.apple.com:443 or api.push.apple.com:443 you should consider that APNs service only accepts connections over TLS1.2+. You can check if your openssl library is up to date or at least supports TLS1.2

@ferigis I get the same error. I tried

openssl s_client -connect gateway.sandbox.push.apple.com:2195 -tls1_2
It returned OK. 

Please suggest how can I resolve this issue. Its pretty urgent issue for us. Please help.

@andyzhou were you able to resolve this issue? Please help me.

hi @monkeyfdude, which apns4erl version are you using? v2+ is for http2 connections and uses different urls

@andyzhou I am using v1. I am trying to migrate to v2 now.
