Data available on ports 30003 and 30005, I've changed source port to 30003 (on one of my feeders had to do the same).
OK this is odd .. it's like he blocked at proxy server maybe .. I can make a direct connection to custom4 over ZT no issue .. Going to take me a bit here ... :/
I changed the HAProxy for the ports .. so it should force the custom port to always be full and use the 30005 anonymous port as failover or if more than one feeder is sending data to the same port. backend custom_51000 balance leastconn server custom 172.19.5.101:51000 check maxconn 1 server cons_30005 feed.adsbexchange.com:30005 check backup
