c++ client: Handshaker factory creation failed with TSI_INVALID_ARGUMENT

[sundar ramamoorthy]

Hi,

I am seeing an issue where a c++ client is not able to connect to the server from one app but it is able to from a different app on the same VM. 

In the working case, in netstat, I can see the right port: 

tcp6 0 0 GRPC-Secure-Test-:58770 xx.xx.xx.xx:8888 ESTABLISHED 

but in the non-working case, I always see: 

tcp6 0 1 GRPC-Secure-Test-:33222 xx.xx.xx.xx:http SYN_SENT 

I am calling the client API from both the apps in the same way. why would the port be set differently than what I have specified in create Channel?? 

Thanks,

Sundar

Sorry, the netstat info. is incorrect. please ignore that. I am still seeing the issue where client is not able to connect to the server from two different apps running on the same VM.

looks like the ssl_context is null in the non working case, any suggestions on how I can fix the issue?
