Is there a problem with my favorite poem? Why can't I open the webpage?

There are four main factors that can't open the webpage:

1. domain name, abnormal resolution, expiration or service termination can all cause the server not to be found. The only solution to this situation is to check the domain name and contact the domain name registrar to confirm the reason.

If the server, space and environment are abnormal, or the service stops, the website naturally cannot be opened.

2. This can be checked by restarting the service IIS, closing some websites, suspending some plug-ins and changing the server environment.

3. For network reasons, if the network is blocked, the website cannot be opened. It is suggested to use Tracert (Trace Routing) to check whether the connected equipment has abnormal delay, and use other line agents to access and test the speed.

4. Client problems, incompatible browsers or abnormal crashes will cause the webpage to fail to open. Just change the browser test.
