receiver disappears

[CapWaldmeister]

Hi, first of all: great work! Thank you. But I have a problem with the connection to my Denon AVR -S750H When the receiver is turned on, I get a connection and everything works fine, I can select the input channel, Receiver reacts accordingly. Also I can switch it off. But after that I cannot switch it on anymore. In the Homebridge protocol the error message "[DenonAVR] ERROR: Can't connect to receiver with ip: ... and port: 8080" In the Homekit control center the corresponding switch shows "No answer". If I restart everything, it works again. But only up to the point where I turn off the receiver in HomeKit once. After that it loses the connection. Even if I switch it on again manually, it cannot establish a connection anymore. I would be very grateful for a tip on how I could fix this.
