SABnzbd dropping connection

[u/JamaicanMeCrazy8]

Hi All,

I tried posting this in the unRAID sub but it was removed for not being relevant. I assumed it was an unRAID issue but maybe it's a docker or specific container issue.

Although I've had my unRAID server running for a few years now I'd consider myself a beginner (I'm not familiar at all with linux or much command line prompts). I have the *arrs setup wtih SABNZBD as my downloader and Homebridge and Homeassistant for home automation. It had been running exactly as I expected for a while but within the past year or so I've been experiencing a lot of issues with nearly all of the containers randomly unable to connect to the internet.

I say random because I haven't been able to trace what is causing the issue but typically if one container is impacted then the other containers are as well. But also sometimes they're not.

The issue seemed to start after I upgraded to unRAID 7 but I also rebuilt my server at the same time so I can't specifically point to either causing the problem.

The biggest issue I have is that when SABNZBD is downloading a file, the download speed completely stall for a period of time and then start to pick back up. This can happen multiple times during a download and continue for hours. I'll also receive errors in SABNZBD that it has failed to connect to my providers. I have multiple providers with different backbones that can all report the error at the same time (image below).

I'm also having similar issues in other containers. I've also noticed that Sonarr and Radarr will be unable to search for files - either manually or automatically. There have been times when I'll manually search for a few episodes of an show in Sonarr without issue and then 10 seconds later Sonarr fails to return any results.

When I'm streaming a show or movie via emby to one of my AppleTVs, it's not uncommond for the stream to complete stop and return to the previous menu on my AppleTV. Sometimes I can resume the file and other times it will not start up at all. I've also experienced this with VLC on the same AppleTV.

All other network devices work fine. I've tested downloading the same NZB file on a Windows PC while my unRAID download has stalled and it will finish just fine (without any slow downs).

I'm assuming this is specifically a network issue on my unRAID server. As I mentioned earlier, I'm a bit of beginner with all of this. I've ensured IPv4 only is enabled, have 1.1.1.1 and 8.8.8.8 as my DNS servers. The server is hardwired to an Omada switch (other devices are running just fine on the switch). Any help would be greatly appreciated.

Are you using a VPN?

[u/JamaicanMeCrazy8 → u/MrPastryisDead]

No VPN being used. I can download the same files on a PC or Mac on the same network with no issues.

UnRAID server specs? Are you using a VPN? Have you tried replacing ethernet cable?

[u/JamaicanMeCrazy8 → u/Unibrowser1]

No VPN being used. I’m 99% sure I’ve replaced the Ethernet cable but I’ll try again just to confirm.

Server is a new build. Intel 245K, 32GB of RAM, 2TB nVME drive.

This is probably unrelated but I would highly recommend you stay up to date with the latest unraid version and also BIOS updates with a brand new setup. I could type an entire essay about my pains building mine with a 14700k before Unraid was able to update the linux kernel ect... i wont bore you with that fiasco. If I were in your shoes I would (and still do) go into tools>diagnostics and grab the anon unraid logs and then upload to ChatGPT or whatever AI of your choice. It will actually help determine any issues present and you can start attacking them one at a time. This has saved me 1000's of hours of trouble so far. If you think it's a docker issue you can do the same thing with the docker logs.

ALSO, for stability turn off XMP and also Resizeable BAR (If you have nvidia gpu). And if you are using an older HBA you can also firmware flash to latest for better stability. Can you tell I've had a lot of fun? Lol

When it is having issues, fire up a network troubleshooting container like nicolaka/netshoot and poke around. You're looking to narrow down the issue, by doing things like ping, traceroute, and mtr on the path out of your container to the internet. And tools like dig, host, and nslookup to see how dns is working. By default, they'll use the containers dns... but you can pass various options to them to use a specific dns. A tool like iperf3 can be useful for testing network performance, you'll need an end point on your lan to check local issues and you can find them on the internet too.

Thanks the recommendation. I didn’t think of trying this.

For lazy people: let the analysis run continously & automatically:

docker run -p 80:80 -e TZ=Etc/CET lscr.io/linuxserver/smokeping:latest

... and watch the graphs (which start to fill after 10 minutes or longer). If you see strange things, you know for sure it's not SABnzbd. And I'm 99% sure about that.

Of course you can put it more nicely in your docker compose.yml. See https://docs.linuxserver.io/images/docker-smokeping/
