Issue with GRPC SSL IOS Library

[acor...@gmail.com]

Hey Guys i have a problem with the ios library.

I am trying to connect through grpc to a golang server that is running grpc and i keep getting an error:

E0119 16:40:21.466024000 123145477918720 ssl_transport_security.c:945] Handshake failed with fatal error SSL_ERROR_SSL: error:100000f7:SSL routines:OPENSSL_internal:WRONG_VERSION_NUMBER.

Message from debugger: Terminated due to signal 15

The server is http2 TLS 1.2 

Is the library doing something different from that by default? I am not able to find any support or help for getting this to work. 

Any help would be greatly appreciated.

This is usually caused by a version mismatch between client and server. Could you provide what versions of client and server are you using?

I did not change anything and it started working once i used a different certificate. Is there a way to bypass the certificate for dev environments? Currently it seems i always have to provide the certificate chain to trust when connecting.
