Port 80 cannot open the website. my website suddenly cannot be opened today and can be opened before. Today I checked and changed the port to another one. The website can be opened. If port 80 is used, it is not enabled. At first, I thought Port 80 was occupied. later, I found that Port 80 was not occupied .. I used the IIS server. later I switched to apache. in the same situation, port 80 cannot be opened, and other ports can be opened. may you please tell me what the situation is and how to solve it!

I used netstat-ano to view

Take a look at the screenshot!

Netstat-ntlp | grep 80
Check whether the Listen setting in httpd. conf is 80.

Port 8081 set in httpd. conf can be enabled with Port 8081.

Take a look at the screenshot!



This port 80 should be the IIS listener. I shut down the IIS service and the port 80 is gone.

Stop iis and add 80 to Listen in httpd. conf.

Well, I tried it. Still inaccessible. Is Port 80 blocked by China Telecom?


Which of the following is the 80 occupied? it shows that my nginx is used and kill it. 6026 is the pid. restart apache and check again.

Port 80 must be filed with the network service provider. Otherwise, it will be blocked.

Is your computer a local computer or a carrier's server?

It turns out that the domain name has been filed and closed!
