Downloaded V 2 today to my MacBook Pro running El Capitan. I previously had EchoHam V 1 and EchoMac installed. They used to work well. With V 2, if I click on Server it loads a list, but when I click on a server, such as Echotest, and then click on connect the screen says, "connecting," then says, "disconnected" a few seconds later. I tried a couple of repeaters and the Echlink test server. They all start to connect, then disconnect.
I tried deleting EchoHam from my firewall permission list; then I reinstalled it on the list. Still no connections. What to do?
