@itsthejb, hello. We've been working on updating the web UI dependencies. Could you please try it on an edge version? It can be reinstalled with the following command:

curl -s -S -L https://raw.githubusercontent.com/AdguardTeam/AdGuardHome/master/scripts/install.sh | sh -s -- -r -c edge

Don't forget to backup the data/ directory and the YAML configuration file.

Hi there,

Thanks for getting back to me. I'm just testing it with the edge version. In my case that's https://static.adtidy.org/adguardhome/edge/AdGuardHome_linux_armv7.tar.gz. However, still seeing the isse.

Is there anything I can do to investigate further?

Thanks

@itsthejb, well, any browser related information is appreciated:

• What browser are you using? What version?
• Is AdGuard Home behind some kind of reverse proxy?

It would also be great to take a look at the browser's console log and the network request information that appears after the buttons are pressed. If you can reproduce it with curl, we'd like to have the command.

Hi,

Thanks for getting back to me. Interesting point about the reverse proxy. Yes, I'm proxying AGH through a Cloudflare tunnel. I just tested hitting the local IP and running the functions and yes, they work as expected.

So the issue would seem to be caused by the tunnel. Quite surprising, because usually straightforward things like this just work. Do you have any idea what might be causing it?

Thanks

@itsthejb, as of v0.107.14 AdGuard Home requires these headers to appear in the request for security reasons, see the change log. Probably the tunnel itself can be explicitly configured to pass them? Anyway, it seems we can close the issue for now.
