I just uploaded a new game two days ago (https://aezart.itch.io/checkers) and there seems to be problems downloading it.
The game has both a web build and downloadable builds available. It was built using Godot 4, so I had to enable SharedArrayBuffer in the itch project settings to get the web player to work.
Enabling SharedArrayBuffer seems to have broken the ability to download the game. This is what I see:
On Chrome (or other Chromium browsers like Vivaldi), after clicking Download on any of the builds, I get redirected to the “Thanks for downloading” page, but no download actually starts.
On Firefox, I get redirected to a page with this error:
Blocked Page
An error occurred during a connection to w3g3a5v6.ssl.hwcdn.net.
On this block page, I can see the full URL of the direct link to the download on the CDN, and if I copy and paste that URL into a new tab I am able to successfully download the game.
I also confirmed that this same issue happens on my friend’s PC on his own network. The only thing we have in common is that we both use Cox as our ISP.
My guess: the cross-origin headers required for SharedArrayBuffer don’t play nicely with the call to the CDN to download the game.
Disabling SharedArrayBuffer fixes the issue, and I’m able to download the game. But without SharedArrayBuffer, the web build doesn’t work so I’m kind of stuck.
