Hi,

Does anyone know what might cause these issues on Adguard Home ?

Probably the WAN/WWAN Internet connectivity is unstable?

Indeed the previous 2.5gb port was unstable and Glinet staff recommended us to change LAN2 to be the new WAN.

If the Internet network stable, the ADG still print these in the syslog?

Please screenshot the Luci - > Network -> Firewall -> Port Forwards:


Are there rules 53 -> 3053?

The Internet network is stable now using LAN2 as WAN but these logs are still being printed:

Is there a fix for this?

Flint is running the following code.

I've got a similar maybe the same problem and there's nothing wrong with my Internet WAN connection that I can see.

Try toggle Adguard home off then on again.

And try updating AdGuard Home as well

I'll ask him, but I think we have done this a few times before.

How do you update it ? via luci ?

I am up to date on firmware and adguard.

I just stopped/restarted adguard, will monitor logs.

I use admon's update utility.

How did that go for you ? Did those logs stop ? If so which step do you think helped ?

Also are you running a VPN ? if so is it NordVPN ?

Thanks a lot.

It did not fix the issue for me.

However when I just logged into my router I noticed that a new firmware update has been released.

I hate to update early so I will probably wait a week or two then update to this code and see if it fixed these log issues.

Bug Fixes

  • Fixed the issue where, after enabling the VPN client and using Global Proxy, enabling AdGuard Home to handle client requests resulted in only localhots 127.0.0.1 appearing in the client list on the settings page.
  • Fixed the issue that TCP port can be probed when WireGuard Server is enabled.
  • Fixed the issue where the 5G wireless disappeared after the device relayed an upstream device with a 5G channel set to 20M dfs.
  • Fixed the issue that resulted in unusual log messages.
  • Fixed the issue where the router's own DNS requests always went through the dnsmasq proxy after switching DNS settings on the page.

Looks promising!

So a couple of follow ups here.

  1. I have not had the problem since upgrading
  2. Coincidentally at the same timeframe my ISP discovered some issues in my area, which they fixed.

So it's hard for me to conclude if it's the ISP fixing micro outages in service or the firmware upgrade that has fixed this.

Thanks
