LLRP Commander - create remote adaptor connection refused to host

[Marcus Gomes]

Hello guys,

I am trying to create a LLRP remote adapter with LLRP Commander. My LLRP Commander is running in a local machine while my ALE is running in a cloud server (AWS EC2). However, when I tried to create the remote adapter "Add Adapter Instance -> IP = Public Server IP -> OK". However, instead of to create the remote adapter I get the following exception in LLRP Commander: 

"Connection refused to host: Private Server IP; nested exception is: java.net.ConnectException: Connection timed out". 

Initially I think that my firewall was blocking the incoming connection, but I made a test by opening all ports and I still get the same exception. After that I figure out that the problem maybe is related with Java, namely the java parameters options that are passed to the application, so I update the CATALINA_OPTS with:

export CATALINA_OPTS="-Dcom.sun.management.jmxremote

                                            -Dcom.sun.management.jmxremote.authenticate=false

                                            -Dcom.sun.management.jmxremote.ssl=false

                                            -Djava.rmi.server.hostname=my.public.ip"

But this not fixed my problem and I still get the same exception when I try to create a remote adaptor. Can you help me fix that issue?

Problem solved, I was passing the public instance IP instead of the instance Public DNS to the CATALINA_OPTS environment variable.
