1, internet speed reason: the website registration entry point is not opened, which may be due to the internet speed. At this time, you can switch data traffic and try to continue to enter.

2. The setting of antivirus software is too high: antivirus software is likely to block the payment success page that pops up after the payment is successful. It is recommended to close the pop-up interception tool that comes with the operating system and try again.

3. Problems with the website itself: Local area network (such as the company's internal LAN) or some wide area networks (such as government network and education network) have security settings, which block this website.
