In the log file i see repeated error "The connection was broken by the other side"
What could be causing this error?

HW: - Ethernet Gateway with ENC28J60 Ethernet module
SW - Scetch from /mysensors/MySensorsArduinoExamples/examples/GatewayENC28J60/GatewayENC28J60.ino

@sandr Looks like your ethernet shield is not stable. After a while failed to write on the socket. So MyContorller closing and reopening the connection.
If you have different ENC28J60 hardware, can you try with that?

@jkandasa
Thank you, i will try.

@jkandasa Problem resolved by connect Gateway directly to my router!
Previously it connected via switch.

@jkandasa

@sandr I believe netty dependent package upgrade might resolve this warning. But I am not sure at this point.
