@chrishamm Yes it was, didn't even think to try disabling that. Thanks!

@stuartofmt I currently use both (Pi-hole doesn't work for some sites, even after adding the domains they use for ads), I will just add an excpetion to the ad-block for the duet page

@chrishamm Duet 3 Mini 5+ in standalone mode, connected via ethernet. The file also loads perfectly fine if I copy the link and open and view it in a normal browser tab.

To add insult to injury, other plugins (Such as the EndstopsMonitor and HeightMap) are showing a similar behaviour. However, it's only the plugins having any issues, the DWC interface otherwise loads and works perfectly fine.

@chrishamm Yes it is built using build-plugin

@Phaedrux Just as I finished typing out a "It just fixed itself" reply, it breaks itself again. I have updated to 3.4.5 and it has not resolved the issue.
The code used in the extension is below

'use strict'

console.log("Test");

const x = async () => {
    const req = await fetch(`${window.location.origin}/rr_model?flags=d99fn`, {method: "GET"});
    if (req.status === 200) {
        const data = await req.json();
        console.log(data);
    }
}
x();
//setInterval(() => {x()}, 1000);

This code loads and runs fine when I run it in a instance built straight from the github Correction: It works when loaded as a built-in plugin

Using DWC version 3.4.2. I have attempted to create a custom plugin, the only problem is, when I load it into DWC it fails to load. DevTools reports that the connection was reset (net::ERR_CONNECT_RESET) but, when loaded in the browser via it's link it loads fine without any issues. I have attempted to clear browser cache, clear cookies, etc with no such luck in solving this issue.

Using a standalone version of DWC built from it's source also results in the plugin loading perfectly fine

Any ideas on how to fix this? I can't seem to find anything I haven't already tried
