model-viewer don't work in Firefox - TypeError: NetworkError when attempting to fetch resource.

[Fabio-Steinberger]

Hello, everyone,
I try to load a glb file with the model viewer, but I always get this error message in the console:

"TypeError: NetworkError when attempting to fetch resource."

However, this message only appears in Firefox, all other browsers work. My model looks like this:

"<model-viewer alt="" src="plugins/modelviewer_jtl/glb/E280608.N.glb" ar="" ar-modes="webxr scene-viewer quick-look" camera-controls="" enable-pan ="" id="mv" camera-orbit="0deg 75deg auto" exposure="2" shadow-intensity="1.48" shadow-softness="0.4" interaction-prompt-threshold="500" data-js-focus -visible="" ar-status="not-presenting">"

Unfortunately I didn't find anything about it. Thanks in advance

Best guess is some kind of server configuration issue (CORS is a popular error, though that will usually show up in the message). Maybe it doesn't like .N.glb? Maybe check the Firefox forums.
