Thanks for reporting @wen911119!

This is an optional check used to see whether or not there's a newer version available, I could at least reduce the timeout to 5 seconds or so. Can you confirm that it works after 30 seconds?

This seems to indicate that Vercel (reactpreview.com's host) is blocked in China, something I didn't expect :(

yes, it works after 30 seconds pending, i can also accelerate it by use a vpn. thanks for your working ！
