WebDev Module: 404 Not Found when accessing HTML via Mounted Folder

Hi everyone,

I am trying to host a static HTML dashboard using the WebDev module. My goal is to use pure HTML/JS for the front-end while keeping Ignition for the back-end, but I am stuck on a 404 error.

My Setup:

  1. Project Name: YS_DB0_VisitDashBoard

  2. WebDev Configuration: I have created a "Mounted Folder" resource named mounted_folder in the Designer tree.

  3. Physical Path: The mounted folder points to a valid Windows directory containing an index.html file. (See screenshots).

The Issue: When I try to access the file via the browser, I keep getting a HTTP 404 Not Found error.

I have tried accessing it via: https://[IP]:8043/system/webdev/YS_DB0_VisitDashBoard/index.html (and also tried including the resource name in the path)

Questions:

  1. What is the correct URL structure to access a file inside a WebDev "Mounted Folder"?

  2. Do I need to configure any specific permissions or "Anonymous Access" settings to make this HTML file visible?

Any advice would be appreciated. Thanks!

Your mounted folder path appears to not be physically in the gateway machine, but in a network share. In Windows, by default, the account running the background service cannot access network shares.

There are numerous discussions on this forum about using UNC paths combined with a custom background user account, like this one:

But it is more robutst to simply place the files directly in the gateway filesystem.

I fixed it, thanks sir
