Hey all,

I’m trying to work out whether I’m hitting a weird edge case or if this is something others are seeing in Unraid 7.2.x.

Setup

• Unraid 7.2.3

  binhex-qbittorrentvpn

• binhex Sonarr / Radarr / Prowlarr / Lidarr / Flaresolverr + Bazarr

• All child containers use:

  --net=container:binhex-qbittorrentvpn

• Rebuild-DNDC at the bottom of the startup order, running on bridge network
  

This setup has been rock solid for a long time.

---

What’s happening

After a VPN/network event, all containers using --net=container:binhex-qbittorrentvpn suddenly show up as “3rd party” in the Docker UI:

• No Edit button

• Can’t update them

• Containers themselves are running fine

• Only way to recover is to recreate them from the existing user templates
  

This has now happened twice within 24 hours.

---

What I’ve found so far

Looking at the Rebuild-DNDC logs, this happens whenever the VPN container’s Docker endpoint ID changes. Rebuild-DNDC then (correctly) rebuilds all dependent containers.

Example from the log:

MASTER container ENDPOINTID DOESN'T MATCH
REBUILDING: binhex-qbittorrentvpn

The rebuild uses normal docker run commands with the same names, paths, and configs — everything works — but Unraid then treats those containers as permanently “3rd party”.

---

Rebuild-DNDC question

I’ve seen a few comments suggesting Rebuild-DNDC isn’t needed anymore in 7.2.x because Unraid will restart child containers automatically?

I tried disabling it for a week test this, but when the VPN container restarted, all child containers lost connectivity and never recovered until manually restarted.

So at least in my setup, Rebuild-DNDC still seems necessary.

---

Curious if others are seeing this

• Anyone else using binhex-qbittorrentvpn + --net=container: seeing containers flip to 3rd party?

• Is this new behaviour in 7.2.x?

• Has anyone found a way to prevent Unraid losing track of these containers?

Happy to share logs if helpful.

if the unraid flash drive lost the template for the docker then this makes sense.

Please run the above script to fix / check.

if the template is still there the webui needs to run the docker update script to resync.

if using docker compose for the dockers then yes its 3rd party theres abactinal lableing to set it to compose...

if it stays 3rd party afterwards the template is gone missing or broken and you will need to reinstall the docker.

The templates are 100% still there - to "fix" them I just add container, choose template, it restarts the container - no longer shown as 3rd party

I don't user docker compose - all were added through Apps

It's very weird because this setup has been running for 4+ years now and never an issue.
However, I've been meaning to get off the binhex- containers for a while because they take minutes to startup hanging on deleting from /tmp every time so this afternoon I've switched to gluetunvpn and migrated all the binhex containers to linuxserver ones - much faster setup. I'm going to keep Rebuild-DNDC turned off and see if this stays stable

So far switching to Gluetun and away from the binhex containers - no longer using Rebuild-DNDC - has been bullet proof, and as a nice side effect a LOT more responsive 👍

You may want to look into the "AutoHeal" docker container.

Thanks. I didn't think I'd need this as everything seemed to be fine - but a week or so later all the child containers started returning bad gateway - had to restart them all by hand
I've added the autoheal container now 😊

A year or two ago I had strange "disappearing container" issues running Rebuild-DNDC so I uninstalled it. Maybe start there.

only if i use docker cli without a internal docker network to connect them... I use compose no issues...

Also is there a reason you’re adding the extra parameter instead of using the network dropdown from the template page?

I wasn’t manually adding it. I was using the dropdown

It was 100% rebuild-dndc. It worked fine for years but now when it rebuilds a container Unraid loses track and thinks it’s 3rd party

Not had the issue at all since moving to a different VPN stack
