openHAB on Synology doesn't work

I installed openHab in my Synology Diskstation with spk package
Running openHab I’ve this error:

2018-01-09 21:32:05.752 [ERROR] [.service.internal.HttpServiceStarted] - Could not start the servlet context for context path [] Address already in use
at Method) ~[?:?]
at [?:?]

Anyway the application starts, but I’m not able to work with RFXCOM transceiver rfxtrx433e.
This is the error:

2018-01-09 21:37:14.200 [ERROR] [g.rfxcom.handler.RFXComBridgeHandler] - Connection to RFXCOM transceiver failed null

Many thanks
