I have created an uploaded my custom modpack to Google Drive and create a direct download link.

I have already setup my modpack's page and configured everything

When trying to download the pack from the launcher, I get the following error:
I know there is something wrong with the link, but I don't know what. It's a direct link and the file itself seems fine. I've been troubleshooting all day and I have no idea what to do next. I have created another modpack before and it never had this issue.
