requires fq to access
your own website. The port is not correct.
ping and access are not the same data. When ping is icmp, it is 80 or 443.
every server has icmp, by default, so there is no problem with domain name resolution, and all can ping. However, 80 and 443 depend on whether the corresponding network service is enabled
the host of the server can Ping the HTTP/HTTPS service running on the IP, server before opening the corresponding website. The protocols and ports used by the two are different. It may also be disabled by the firewall. It is recommended to first check whether the service and port are open, and then check the firewall settings. It is not possible to catch the packet and analyze the reason.
