This is not a quick failure, I have spent a totally of 5 completely full days trying to figure this out. Initially I was limited by file size and then file type; in which I removed the Wordpress restrictions and am now "capable" of uploading my 177MB .glb file to Wordpress.
However when doing so, I receive the following error:
retriever.glb
Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.
I was on the phone with GoDaddy Specialists for 2.5 hours yesterday ensuring that this was not a Server issue or restriction on their side.. they confirmed that it was not. We pretty much ended the conversation that it is something I must figure out with me, myself, and I.
I went ahead and uploaded my .glb to the server through panel, everything worked fine. In fact I have a location for it here: https://www.tattiniboots.com/wp-content/uploads/2020/07/retriever.glb
However, this does not make the file discoverable to the 3D viewer plugins I have installed on the site through the media location.
I truly don't know where to go from here
I changed the name of the file to .png and attempted an upload and received the following error:
Post-processing of the image failed likely because the server is busy or does not have enough resources. Uploading a smaller image may help. Suggested maximum size is 2500 pixels.
I just tried to update a normal .mov file that is 150MB and received the following error; really making me think this is something to do with file size:
Unexpected response from the server. The file may have been uploaded successfully. Check in the Media Library or reload the page.
Yes, normal images are uploading just fine (2MB-ish)
I just attempted to deactivate all plugins with consideration that maybe "Smush" or another was imposing issues: I then received the issue that the file type is not supported (even with the allow all file types code in my wp-config)
Is this just the case that glb is not allowed at all?
This must be a server thing. probably a run time error
Whoever supported you just doesn't know it. GoGoDaddy. ;)
Nevertheless... you can Use a plugin that's called
media sync. Check it out and best of luck
