Does it happen everytime you check update or occasionally?

I think this error may occur because you are in China😂 so unable to fetch the actual json value. We are considering moving some direct link to github to cdn, but haven't completed.

We are considering moving some direct link to github to cdn, but haven't completed.

@taooceros it's done/fixed in the dev branch right?

The issue for China is not. However, I am not sure how to fix it....
