Im using OSMC on my RP2, and running Kodi on my iMac.
im using phpmyadmin on my synology NAS, and using advancedsettings.xml to share the watch status between my 2 setups.
it has worked perfectly for a couple of months, but this morning, when i wanted to update my library it sad something like “unable to connect to remote server, do you still want to search” . both my setups (RP2 and iMac) is saying this, and now they dont share the watch status anymore…
anyone with any idea what the problem could be ?
Sounds to me like the Synology NAS is to blame, since you say you get the ‘unable to access server’ on both Pi and iMac.
Perhaps an automatic update is responsible - the Synology seems to bug users in all sorts of situations (see other forums)
