"This Disney+ failure happens while the likes of Netflix, Amazon Video, and Hulu work fine due to a difference in their Widevine handling. Linux browsers (as well as some Android devices) only support Widevine Level 1 while Disney+ requires the highest level security features thereby blocking out the support."

from hans himself:
...So I subscribed for the testing period, problem all devices in my home run Fedora. I started up Firefox and was greeted with an "Error Code 83", next I tried Chrome, same thing.
So I mailed the Disney helpdesk about this they eventually got back to me in about a week. They wrote: "We are familiar with Error 83. This often happens if you want to play Disney + via the web browser or certain devices. Our IT department working hard to solve this. In the meantime, I want to advise you to watch Disney + via the app on a phone or tablet. If this error code still occurs in a few days, you can check the help center ..." this was on September 23th.
Their so called help-center does not even know about "Error Code 83" even though the internet is full of people experiencing this. Note that this error also happens a lot on other platforms, it is not just Linux.
Someone on tweakers.net has done some digging and this is a Widevine error:
"the response is: {"errors":[{"code":"platform-verification-failed","description":"Platform verification status incompatible with security level"}]}".
Widevine has 3 security levels many devices, including desktop Linux and many Android devices only support level 1.
In this case e.g. Netflix will not offer full HD or 4k resolutions, but otherwise everything works fine, which is a balance between DRM and usability which I can accept.
Disney+ OTOH seems to have the drm features kranked up to maximum draconian settings and simply will not work on a lot of android devices, nor on Chromebooks, nor on desktop Linux."
