Ummm, that sucks. I know I had some issues with getting Sonarr working on my ReadyNAS 516, and so I gave up for a while and tried again for a couple times and now it seems to be working great. It’s just figuring out what the issue is. It was really nice to unload everything off my PC, and that included V.I.S. which is software for my Acu-Rite 5 in 1 weather station software where it uploads Data to the Weather Underground and other sites. It’s great Windows software if you have a Acu-Rite. Then I found out about Meteobridge and how I can install it into a small Wifi Router. In my case I got a $20 D-Link DIR-505 and installed this FIRMWARE onto that. It can report to even more places then V.I.S. could and I really don’t even have to think about it. Set it and forget it. The Software is around $75 but it’s lifetime on the device, where V.I.S. I had to pay every year. That was the last thing I had to worry about and now I can just turn off my power hungry PC. That Mini Router only uses around 1-2 watts of power.
So I was using SickRage on my NAS and it works pretty good, and it’s still installed. Right now it’s turned off, but I can turn it on again at any time quickly and it’ll start working again. So maybe that’s a option to try? It’s not as power hungry and doesn’t require MONO. Use that until you can get Sonarr working as it should on the NAS. SickRage is still getting supported. I get Updates from it all the time with just a click when it’s running. I turned it on yesterday just to see if there was a update and there was, so I installed it and then turned it back off again.
That would free your PC for now. SickRage does a few things Sonarr doesn’t like download Sub titles for shows. So I was doing English and a few others for some other people that watch my content. When it finds it for a program, it’ll grab it. So that’s kind of handy. Overall I like Sonarr better. It’s just a option. You may want to just check it out and see if you have any better results with it. I think Sonarr does a better job at grabbing shows overall then SickRage. It doesn’t hurt to try.
It does require Python 2.7.10 which you more then likely are already using with some of your other programs on your NAS.
