Two desktopcomputers, both on the same internal network, both running Ubuntu16.10.


One of thesecomputers (“S”) is running a couple DLNA/UPnP servers: Subsonic,and Emby. The other computer (“C”), is running Rhythmbox 3.4.1,with the “Grilo” plugin enabled. I am logged into Ubuntu on bothcomputers, and Rhythmbox is running on computer C. I h ave verifiedthat the DLNA/UPnP servers on computer S are in fact running.


In the past, when Istart Rhythmbox on computer C, via the “Grilo” plugin Rhythmboxwould “see” the DLNA/UPnP servers on computer S, and would beable to access the songs on computer S and play them in Rhythmbox oncomputer C.


Recently, and Idon’t know why, it seems that Grilo has stopped working, becauseRhythmbox on computer C no longer even “sees” the DLNA/UPnPservers on computer S.


I have lookedonline, but could not find anything that would help with mysituation. I appreciate any ideas on how I can diagnose this problemand get it fixed.
