Description of issue: I’ve been using Sonarr on my Synology NAS (DS415+) since I got it several years ago. It’s worked fine until this recent update (or could have been the recent mono update). Now I get an error saying Missing root folder. If I try to add a series manually when I click to browse, Sonarr cannot see the folder where I store all of my TV shows (/volume1/video/TV). I can browse to /volume1/video, but it shows no folders under that, and there are many. I have no idea what could be causing this. Interestingly, it can see some other shares I’ve set up, and I’ve checked the permissions, and they’re actually stricter for those shares than the video share, so it should be able to see anything under that share. I also tried to browse in Radarr and the same thing happens, it doesn’t see sub-directories under video. I’ve tried rebooting the NAS, restarting Sonarr several times, nothing works. I’ve linked to the logs. Hopefully someone can see what is going wrong here. Thanks!
