400 Bad Request(validating dns config: private upstream servers: no upstream specified

Open masterlog80 opened this issue 1 month ago • 6 comments

What happened?

Hello, I am using AdGuard Home sync with a couple of small VMs (on Proxmox) running AdGuardHome with no issues. Recently I have created a container on Docker running AdGuardHome (adguard/adguardhome:latest), I have set it up and added its configuration settings to AdGuardHome-sync (this run in a different Docker server). As result, the sync process fails with Errors, and the configuration is not synced (there are just default settings left). I am not sure if the issue with container itself (but it's just deployed on docker per its public documentation and using Network "macvlan" so all the ports are exposed) or something else. The other instances of AdGuardHome (on the VM Instances) keeps syncing.

Steps To Reproduce

  1. Create a new instance of AdGuard home on Docker: https://hub.docker.com/r/adguard/adguardhome
  2. Set the Network as "macvlan"
  3. Complete the configuration per http://IP_ADDRESS:3000
  4. Edit the configuration for AdGuard home sync by adding the details for the new AdGuard home instance
  5. Recreate the Container
  6. Manually start the sync and check the logs

Hi Either you need to define upstream dns servers in your Adguardhome origin, or disable the serverConfig feature.

bakito avatar Nov 14 '25 05:11 bakito

Thank you for getting back @bakito, As per I can see, Upstream DNS servers on the Adguardhome origin are definitely set (should be the default ones). Image To be more correct, the configuration on origin and replica are most the same as i kept the default configuation (apart DNS rewrites which is what I want so sync).

However, disabling the serverConfig settings fixed the issue, but it's very strange this occurs only with AdGuardHome running on Docker, and not the other ones. My final goal would be to sync all the settings.

Regards,

Could you provide debug logs of the error? https://github.com/bakito/adguardhome-sync/wiki/FAQ#how-do-i-get-debug-logs

Sorry for the late reply. I have collected the debug logs as below (I have replaced the username with the string <USERNAME> and other details, and set serverConfig: true to replicate the Error):

I hope this can help! Otherwise, I may suggest to replicate this locally, as I have also shared Docker configuration.

I am experiencing the same issue as well. my setup is an origin of a proxmox lxc adguard instance. This successfully syncs to the other LXC instance. I have one other instance it syncs with which is a docker image from adguard/adguardhome:latest. This syncs everything, but the upstream dns servers. I could disable and the error goes away, but the main thing im trying to sync is the upstream servers which is part of that config.
