LMS on Qnap HS210 issues

I'm running LMS 7.7.2 on my Qnap HS210 but it's already long time that is giving me troubles. Basically the Duet receiver cannot connect to the server anymore even if from the Qnap control panel seems that LMS is running. Strangely LMS is not reachable if I click on the relative icon (ERR_CONNECTION_REFUSED).
Where can i find an updated and reliable LMS to install on my nas? There is any other solution or I have to change the NAS/Squeezebox?
Thanks in advance for your help.
Cheers
