It seems like your client is not able to verify the server certificate against 
your trust store. I had this kind of problems using proton-j the last days, but 
this had to do with client authentication with a certificate.
You could try to use openssl to check that, e.g. openssl verify -CAfile <file 
containing the certificates of your trust store> <server certificate>. See for more details.

Betreff: Re: Proton-c SSL Connection

I figured out some of the issue, and I believe that it had to do with the 
client not finding the proper trust store. I am now getting the following with 

[0x1d45e00]:  -> AMQP
[0x1d45e00]:0 -> @open(16)
[container-id="dc8f96e5-4f0f-4944-8793-acec19793c40", hostname=""]
[0x1d45e00]:0 -> @begin(17) [next-outgoing-id=0, incoming-window=2147483647, 
[0x1d45e00]:0 -> @attach(18) [name="topic://test", handle=0, role=true, 
snd-settle-mode=2, rcv-settle-mode=0, source=@source(40) 
[address="topic://test", durable=0, timeout=0, dynamic=false],
target=@target(41) [address="topic://test", durable=0, timeout=0, 
dynamic=false], initial-delivery-count=0]
[0x1d45e00]:0 -> @flow(19) [incoming-window=2147483647, next-outgoing-id=0, 
outgoing-window=0, handle=0, delivery-count=0, link-credit=1024, drain=false]
[0x1d45e00]:0 -> @close(24) [error=@error(29) 
[condition=:"amqp:connection:framing-error", description="SSL Failure:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify 
[0x1d45e00]:  <- EOS
[0x1d45e00]:  -> EOS

Any thoughts as to what may be causing it?
