Can't connect via telnet after update

[dppeak]

Keep getting the following error after updating to the latest release.

{ Error: connect ECONNREFUSED 192.168.1.210:23
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1083:14)
errno: 'ECONNREFUSED',
code: 'ECONNREFUSED',
syscall: 'connect',
address: '192.168.1.210',
port: 23 }

I am able to use the AVR Remote app to connect to my AVR-X1300H. The X1300H is on the network and communicating properly with my Control4 system as well.

Unfortunately, only one connection via Telnet is possible. Is it possible that another device also accesses the interface?
