Have you tried just pulling a new copy and seeing what happens after you set it back up? One other time, I had some issue, and that that per this document and that fixed what was wrong with my setup.

hm this will not fix my sound issue

That happened to me and I believe Steven had me run this to fix it.

git submodule update --init --recursive

And I believe you run that from the frontend folder.

Then recompile the frontend.

NovaSDR 0.3.0 + 0.3.1 Released

0.3.0 - New: Operator "About this receiver" header panel You can now enable an optional expandable section in the header with operator-provided information. It's driven by an overlay file so it's easy to edit without touching the core config.

• Header panel overlay via config/overlays/header_panel.json (auto-created, disabled by default)
• Manual content using items[] (label/value rows you control)
• Optional donation button using donation_enabled
• Optional widgets (toggleable): HAMQSL solar-terrestrial + Blitzortung lightning map
• Optional lookups (toggleable): QRZ callsign, MWLIST frequency, short-wave.info frequency
• Wizard support: the setup wizard can configure the overlay and related options

0.3.0 - New: Reverse proxy port for SDR lists If you're behind a reverse proxy and the public port differs from server.port, you can now set:

• websdr.public_port to advertise the correct port to SDR lists

0.3.0 - Compatibility and auto-migration Older configs remain compatible, and NovaSDR will help keep them current:

• Legacy server.html_root: "html/" is migrated to "frontend/dist/"
• Missing websdr.public_port is auto-added as null

0.3.1 - Polish: Header panel layout improvements 0.3.1 is focused on refinement and usability:

• Cleaner spacing and typography for the expanded header panel
• Better mobile responsiveness (fixes overflow in callsign/frequency rows)
• More consistent widget/image placement to avoid awkward empty space

Quick note on images Place images inside the UI directory (server.html_root, usually frontend/dist/) and reference them by filename in config/overlays/header_panel.json. Example: if the file is frontend/dist/test.png, use "test.png" in the overlay.

Thanks for testing If anything looks off on a specific phone/tablet/browser, post a screenshot and your header_panel.json (feel free to redact URLs).

Thanks Steven, this is great!
Much cleaner than the previous version.

There is only one small problem, at least for my flag,
next to my call sign and my colleague 9a3szf
is a Slovenian flag, not a Croatian one.

The Croatian flag has the same color scheme as the Dutch flag,
except that it also has a coat of arms with a checkerboard.

Please, if you can fix that little thing.
Thanks!
