Starting Nginx Nginx Error Send Failed 111 Connection Refused
What Is Nginx?
Nginx is an open-source web server software that was first released in 2004. It is incredibly efficient, fast, and secure. It is largely used to handle web traffic and can also serve as a reverse proxy, load balancer, and mail proxy. It is widely used due to its high performance and flexibility. Many of the world’s largest and most visited websites are powered by Nginx.
Common Causes of the “Send Failed 111 Connection Refused” Error
The most common cause of this error is an incorrect configuration for Nginx. Nginx will typically respond with a “send failed 111 connection refused” error when an application attempts to access a resource that is not allowed. This could be due to misconfigured security settings, like blocklists, firewall rules, or authentication. Other common causes of this error include misconfigured server settings, excessive connections, or a lack of resources available to the server.
How To Troubleshoot the Error
The first step in troubleshooting this error is to check the Nginx configuration. Double check that all settings are correct and that they’re pointing to the correct resources. If this doesn’t solve the issue, then there are several other steps that can be taken.
If the ERROR shows a specific IP address in the error message, then the connection should be blocked from accessing the server. This can be done by adding the IP address to a block list or an access control list.
If the ERROR message does not show a specific IP address, then the next step should be to check the Nginx access logs. These logs will contain information about every single request made to the server. This will help to pinpoint which requests are causing this error.
If the problem persists, then the next step should be to check the server resources. If the server is under excessive load or out of memory, then the connection could be refused. Take the appropriate steps to reduce the load on the server. This could include reducing the number of active processes, optimizing the performance of the server, or upgrading the server’s hardware.
How To Prevent the Error in the Future
To prevent the “send failed 111 connection refused” error in the future, the following steps should be taken:
- Ensure that Nginx is configured correctly
- Regularly check the Nginx access and error logs for suspicious activity
- Regularly check the server’s resources to ensure that it is adequately provisioned
- Ensure that all necessary ports are open and accessible
- Regularly review and update security settings, like blocklists, firewall rules, and authentication
