Slow reading logs core 2024.11.0

Yesterday discovered that I have something strange when I want to read the logs of supervisor, hosts, dns etc via settings → system → logs.

When I use the direct link [http://homeassistant.local:8123](http://homeassistant.local:8123/ the response is instantaneous, when I do it via my normal setup via reverse proxy either I get “Failed to get supervisor logs, NetworkError when attempting to fetch resource.” and nothing more or I get “Failed to get supervisor logs, Error in input stream” and the lines of the log are still displayed.

This seems to have been introduced by HA Core 2024.11.0 as when going back to 2024.10.4 I do not see this behavior.

I dug around and added some entries to reverse proxy but I can see no difference so far. Also not really finding anything with the error strings online.

Today even before 2024.11.1 being applied it was working as expected again so not sure what was going on in the mean time

I have the same issue with accessing logs from addons on 2024.11.1.
Using http://lan_ip_address_here:8123 in Firefox 132.0.1, also tried Chrome 130.0.6723.117, both on macOS. First I thought it is something related to my addon but checked against “Advanced SSH & Web Terminal” addon with the same result.

Exactly the same problem, however access to port 8123 works without any problem. I would susspect some reverse proxy settings.
