Yes, this is the exact issue I have. However, may have narrowed it down to a smaller .js file and that file not having their MIME-Type set. All of the other scripts have a proper MIME, but this one does not:
I see errors in 3 .js files:
CyjJQS-n.js
DcQYf4Dz.js (MIME TYPE is not listed under Chrome/Safari. But in Firefox it is shown as Text/javascript)
B_4WZ4t6.js

This is exactly the error I see here in SC.

One of the challenges from support was that they only had my support ticket on this subject. While I tested on countless systems/networks, they could not reproduce the problem. When I sent several videos of me asking completely random people to try on their network, I think they had a starting point. I say this so affected users will actually open a support ticket and let them know as much as possible about browser/ISP, etc. I know IT can be tough, so perhaps this will help.

Hey CSpill, I am the one who reported it. I am in the southeast USA. Please pass on as much of your situation to the support staff at Maxon. Perhaps if they discover others who have reported the issue, they can narrow it down. I have been getting help, but it still hasn’t worked completely.
I did find a work-around. If I use the Firefox web browser, the site loads fine. I have many theories, and have shared them with support, so hopefully they will be able to figure it out.
Try Firefox, it may work in the meantime.

Thanks again. I did not know about the zip file restriction. I made the .har Google Chrome archive, but I couldn't upload it to the Zendesk on the support-side ticket, so I tried zipping it. I have uploaded the original .har file to the google drive share above and the rtf file which explains what my research discovered.

I want to thank you for your rapid response. Indeed, your patient and kind responses are the gold standard in support.
As I walked into work today, I asked a random person to try their cell phone to browse to the site. It failed on their Verizon iphone using Safari just as it does on several networks.
I would like to share the video screenshot I have to show the error, along with the google chrome html archive. I also have a .zip file which has a possible explanation of why this occurs at only certain locations.
Would you be willing to pass the files on to your IT Personnel?

I cannot get Cineversity to load any sub pages on several networks here in the USA. For more than 15 days, the issue happens at the school’s AT&T network as well as TMobile WiFi or cellular or at several locations. I was able to get it to work when connected to a Spectrum ISP network.
Chrome and Safari report an error:
500 Failed to fetch dynamically imported module: https://cineversity.maxon.net/_nuxt/B_4WZ4t6.js
or
500
'application/octet-stream' is not a valid JavaScript MIME type.

Although Maxon support says it is on my end, 500 errors are on the server side.
After inspecting the site with Chrome Dev Tools,
The error message inside Chrome points to a Content Security Policy directive set to "script-src 'none'"

This causes the nuxt.js generated script (and subsequent scripts), CyjJQS-n.js, to not load and the site to fail to load on any browser which enforces CSP directives, such as Chrome or my Safari.
I believe it may be the CDN Maxon uses in my area, because if I change my geo location to Germany, the site opens fine.

I know this problem exists.
I know the issue is outside of my control.

If anyone can help, can you reach out?

I noticed a change to how the project files are shared. I get a message about logging into Dropbox. I created an account at Dropbox with the same email as my maxon account, but it still says I don't have access to the project files. How can I access project files? I am a part of the Maxon Teams Account Group. I have 32 licenses of Cineversity.

Thank you for your rapid reply. Your example file helped quite a bit. The use of reference materials was helpful. When I used it, I still had trouble with the fact that one material had a different projection than the other. This then reminded me of an older shader-graph method for showcasing stickers/decals/etc. I ended up using a UV Projection Node between the displacement texture and the Displacement node. Then I combined them in the Displacement Blender. While it doesn't appear to mix as easily as Color Layers do, the result did allow me to indent into the leather.

Thank you again.

Dr. Sassi,
I have been working through Elly Wade’s Tutorial on rendering Redshift Basketball. My intention is to add a team logo, and change the ball’s logo to Wilson to match our High School’s ball. My challenge is that I cannot properly stack the materials’ displacement when my logo is Projection-Flat and the Basketball’s displacement is UVW Mapping. It appears to do one or the other. I have tried to create a UVW from projection, but when I apply it to a Displacement Node, the surface textures become flat as well.

In my shared file, I have placed 2 duplicates of the same ball. The left one has proper UVW displacement in the leather (from the Basketball Material) but the Logo appears simply painted on, with no indentation. The one on the right, has displacement, so we can see the depth (displacement is in the right-most material "RS Wilson Logo Gold Trim"), but the general displacement of the leather is from a frontal projection. This is visible from above where there is the displacement stops.

How can I make the ball look like the example on the left for the leather, but have the impression/indentation like the basketball on the right?

@Dr-Sassi Thank you so much for you swift reply. I will investigate these suggestions. I am also pleased to see that the Maxon Developer's Cafe is a thing. I did not know there was such a thing. Thank you again. (Have you checked your drone for new firmware? My DJI Mavic 2 Pro supposedly has a new Remote ID firmware)
