How is Dozzle deployed?

Standalone Deployment

📦 Dozzle version

v10.6.6

✅ Command used to run Dozzle

The download button exists, but Chrome blocks the async programmatic download (as diagnosed by Claude after working with it to make the download button work).

🐛 Describe the bug / provide steps to reproduce it

I tried to download Sonarr logs from Dozzle. The download button creates no action. I had to use the container ID to download it from Docker.

Download works for me. Are you using http or https? I need the logs for the browser.

[Florentina72]

I'm using HTTPS via Caddy reverse proxy (Cloudflare Tunnel → Caddy → Dozzle).
After clearing the console and clicking the Download button:

No output appears in the console — no errors, no logs, nothing at all
No network request fires in the Network tab
The single error visible (A listener indicated an asynchronous response...) appears before clicking Download and is from a browser extension, not Dozzle

The element is present in the DOM with the correct href (/api/containers/e3fe116b-6a19-4bb3-a388-ecf9fb7e34e3~771b5b4247eb/download?stdout=1&stderr=1). Navigating to that URL directly in the browser works and downloads the file successfully.

I am not able to reproduce this at all. I have used chrome, firefox and safari.

• What browser do you have?
• Can you try without any extensions?
• What is exactly happening? Nothing? Does the url work directly?

Anything else to help me diagnose the issue would be good. The fact that nobody else has this issue makes me suspicious that something is specific to your setup.

Hi Amir,
Thanks for looking into this. The download button does work in Vivaldi, but the experience is confusing for two reasons:

Silent download — Vivaldi is configured to ask for a save destination on every download, but Dozzle's download bypasses this and saves silently to the Downloads folder. This appears to be because Dozzle uses a programmatic Blob download (fetch → Blob → .click()) rather than direct URL navigation, which bypasses Vivaldi's download preference.
No console feedback — Clicking the Download button produces absolutely no console output — no logs, no errors, nothing at all. This makes it impossible to tell if anything is happening, which is what led me to think it wasn't working.

The direct URL works fine. The issue is specific to Vivaldi and the silent nature of the download with no visual or console feedback. Not a blocker, but worth noting for other Vivaldi users.
Thanks again for your time!

Oh sorry. I missed this for some reason.

This makes sense. Perhaps I should just forward to the URL. I didn't test Vivaldi before.

@Florentina72 after looking at this, the download button doesn't use blob. And I tested in Vivadli. It works as expected. It start downloading right away. I am just sending the user to the download link directly.
