Multiple problems with latest builds

Hi @ds_2, Welcome to the Roon forum, sorry to see you’re having issues, I’ll try to add a little info to help:

I suspect the Tidal login issue causes most of your remaining issues. Roon reaches out to Tidal for searches and an overview. Adding Tidal albums will also fail if there’s a connection issue. If there is some kind of network blocking on your core (as suggested by the Metadata improver issue) that might also cause the Tidal issue?

Finally, depending on your tech know-how and bravery, this link Synology Linux Roon Server cache delete might also help (remove cache contents). For extra reference the contents of my cache directory (NUC with Debian an RoonServer) looks like this:

ls /var/roon/RoonServer/Cache/
devicedb-prod.zip  devicedb-prod.zip.etag  httpcache_2.db  httpcache.db  qobuz  qobuz_1.db  sessions  smc.db  tidal_2.db

I hope some of this is useful.
