The telnet test on port 80 of the server is successful, but the web page still cannot be opened.

Question

Please give me some guidance. The telnet command test on port 80 on my server is working.

But I still cannot access my webpage through the external network. The server can access it locally

What is the reason for this, please guide me

Find your network service provider (Telecom, China Unicom, etc.) to open port 80. All networks now close port 80 by default.
