Hi there,<br><br>We need to upgrade our messaging server from 1.8.0 to 2.7.1. To ensure a smooth transition, we are trying to make the two rabbit server versions coexist on the same machine, so we can have our existing messaging system running while having our new messaging system being tested in the same environment, This also ensures minimal interruption for the transition in the production environment as well.<br>
<br>I grabbed the rabbit 2.7.1 source and changed the location of rabbitmq_env.conf, so that I can specify a different environment for the new rabbit server. <br>These are the env variables I specified in rabbitmq_env.conf:<br>
<span style="color:rgb(0,102,0)">SERVICENAME=</span><br style="color:rgb(0,102,0)"><span style="color:rgb(0,102,0)">NODENAME=</span><br style="color:rgb(0,102,0)"><span style="color:rgb(0,102,0)">NODE_PORT=</span><br style="color:rgb(0,102,0)">
<span style="color:rgb(0,102,0)">CONFIG_FILE=</span><br><br>Now I've got 2.7.1 running alongside 1.8.0. The problem is that although I have SSL configured for 2.7.1, only non-SSl connections currently work. For any SSL connections, I get a "connection refused" on the client side. I triple checked the SSL certificates and saw no problems. However, when I list the status of the 2.7.1 server , it says the following:<br>

<br>What are my options here? Would updating Erlang on ServerA to the latest version solve the problem? Would the latest Erlang be incompatible with rabbitmq 1.8.0? If I were to still use Erlang R13B03, what shall I do to make 2.7.1 work with SSL?<br>
