Hello wangjianhui,

We see you're having issues launching a particular page. We'd be happy to help.

This page can help with those types of issues: If Safari on Mac doesn't open a webpage or isn’t working as expected

Be sure to also check for any extensions that may be interfering.

If possible, you can also try using a different web browser to test it out there.

See if you're able to access the page from another device as well, to rule out issues with the current one.

Cheers.
