Causes of ‘Apache Http Server Connection Refused’

🔥 How to fix it: You can fix this issue by opening the port on your firewall. You can also disable your firewall temporarily to see if it is causing the issue. However, we recommend configuring your firewall rather than disabling it.

2. Incorrect Port Number

Another cause of the ‘Apache Http Server Connection Refused’ error message is an incorrect port number. If you have specified the wrong port number on your Apache server configuration file, you may experience connection refused errors.

⚠️ Note: The default port number for Apache Http Server is 80.

🔧 How to fix it: Make sure that you have specified the correct port number in your configuration file. You can also check if the correct port number is open on your server.

3. Server Not Running
