Possible Telnet issue with Update 2.3.9.193

Sorry, a little more info may be helpful. My Russound can be controlled by the iTach IP2IR Hubitat driver. I figured out that HE/webcore can use that driver to directly send telnet commands to my Russound and control it. No IR is involved. I use webcore to send those telnet commands. For some reason, the telnet connection would only stay active if commands were being sent. If that connection sat "idle" for > 1 hour, it would disconnect from my Russound. So, I have been sending a "mute" command to the Russound every hour. That has worked well to keep the telnet active. On occasion, I would have to reboot the Russound, maybe once a week or so, when the telnet connection became "disconnected." I have a webcore piston that monitors that connection. And when it becomes "disconnected", it reboots the Russound and checks the connection again. That has been working relatively well. But after the Update to 2.3.9.193 or maybe a little earlier, rebooting the Russound would not reconnect the telnet, forcing me to reboot HE. And that worked. But lately I have to reboot HE every day, sometimes more than once a day, because the telnet becomes "disconnected." I'm not sure if this problem is from the update, my ancient, failing Russound, my coding, or some combination all all of that. But the WAF has greatly decayed. I hope this helps.
