On recent downloads, the Dashboard Server doesn't display on web browsers

[SysIntFL]

Environment

• Windows or Linux (Mint)

Describe the bug

On any recently downloaded/installed version of Chataigne (GUI appears properly on PC's that had Chataigne installed in October), the Dashboard Server will not display properly on a web browser, just displays black. Doesn't matter if I try with a local browser or external.

When the Dashboard Server browser page is put into Inspect mode, the network tab shows only 2 processes and they both have an error code of 404.

With a locally opened browser, I can access an external PC running Chataigne (that was installed in October) and Dashboard Server appears on the local browser properly.

To Reproduce

Download any version of Chataigne for windows or linux and try to bring up the Dashboard Server on any web browser.

Expected behavior

In any web browser, I should see the Dashboard Server of a Chataigne program that I have accessed.
