If the server cannot accept the connection request or refuses the connection, an ERR_CONNECTION_REFUSED error will occur.

So, what exactly does ERR_CONNECTION_REFUSED mean? This may have the following situations:

1. The server is not running: When the server is not running on the specified port, the ERR_CONNECTION_REFUSED error occurs. This may be because the server encountered a problem or the administrator shut down the server.

2. Firewall Blocking: A firewall is a type of security software used to protect computers from malicious attacks. Sometimes, firewalls may block connection requests to certain websites, causing an ERR_CONNECTION_REFUSED error. This is usually done to prevent users from accessing websites that may contain malicious code or illegal content.

3. Network Issues: Often times, errors occur due to network connection issues. This may be due to the user having an unstable network connection, or due to some issue in the network preventing the connection request from reaching the target server.

How to solve the ERR_CONNECTION_REFUSED error?

1. Check server status: First make sure the target server is running and not experiencing any issues. You can try accessing the same website from another device or network connection to determine if the problem is server-side.

2. Confirm firewall settings: If you are using firewall software, check its settings and make sure they are not blocking connection requests to the target website. You can try to add corresponding exception rules in the firewall to allow connections to the target website.

3. Check the network connection: Make sure your network connection is stable. You can try restarting the router or using a different network connection to test whether the connection request was successful.

In general, the ERR_CONNECTION_REFUSED error means that the browser cannot connect to the target server. You can try to resolve this issue by checking server status, confirming firewall settings, and checking network connections. If none of the above methods work, there may be a problem with the target server and you need to contact the website administrator for further resolution. .
