404 Not Found
The website causes a 404 error that does not mean that the data is requested.

There are two reasons:

1: The page does not exist on the origin server

2: The request is not made by the origin server

Generally, the first case is larger. The second case is usually due to switching DNS resolution records, resulting in the request being the old address, not the new address.

It is estimated that there are DNS cache servers in general provinces and cities across the country, which means that DNS resolution records are cached on the DNS servers of provinces and cities, and there is no need to request from the root DNS server every time

Generally, the effective time of domain name resolution is 10 minutes, the time of saving DNS cache server is 10 minutes, and the time of municipal DNS cache server is 10 minutes, etc

Therefore, when resolving a domain name, you will be prompted to take effect within 2 hours, which is due to the time setting of the DNS cache server.

Solution: Locally connect to the DNS server and set it to a relatively large DNS resolver, for example: 8.8.8.8
