Local file issue

Post by **danielhb** » 2026-02-22, 20:46

I have an HTML file; it's a Kanban project. If I open it on my website, there are no problems, but if I open it on my desktop PC (Mabox linux), after about a minute it tries to connect to an address similar to 0.0.0.2 or 0.0.0.9, etc.

Here are the first few lines of the HTML:

Code: Select all

!DOCTYPE html>
<html lang="es">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="x-dns-prefetch-control" content="off">
    <meta http-equiv="Content-Security-Policy" content="default-src 'self' 'unsafe-inline' data:; script-src 'self' 'unsafe-inline'; img-src 'self' data: https://orquidealucinada.net https://img.shields.io; connect-src 'none'">
    <link rel="icon" href="tucan.ico" sizes="any">
    <link rel="icon" type="image/png" href="tucan.png">
    <title>Mi Kanban</title>
    <script src="marked.min.js"></script>
    <style>
    ...
    ...

Any idea what's going on?

Thank you very much.

When I copy your given text (less ellipses) and supplement with </style><body>Hello, world!</body>, saving this as a local text file, the file loads properly. Is there anything sensitive in the document which precludes you uploading the whole file to test?

Probably the software trying to phone home.

I wouldn't immediately ascribe it to something malicious.
If it's part of a web application (which Kanban seems to be by definition), the back-end may simply be trying to communicate with other parts of the system. We just don't have enough information to draw any conclusion without actually looking at the javascript involved and knowing how this particular system works.
