Fixing java.net.socketexception: socket failed with permission denied (eacces) error

If you are a Java developer, you may have come across the java.net.SocketException error in your application. This error occurs when a socket tries to connect to a remote host but fails due to a permission denied error. This error can be frustrating, especially if you do not know how to fix it. In this guide, we will provide you with a step-by-step solution on how to fix the java.net.SocketException: socket failed with permission denied (eacces) error.

Step 1: Check the Firewall

The first thing you should check is your firewall settings. If the firewall settings are blocking the connection, you may receive the java.net.SocketException error. To fix this error, you need to allow the Java application through the firewall.

Follow these steps:

  1. Open the Control Panel.
  2. Click on System and Security.
  3. Click on Windows Firewall.
  4. Click on Allow an app or feature through Windows Firewall.
  5. Click on Change settings.
  6. Check the box for Java(TM) Platform SE Binary.
  7. Click OK to save the changes.

If the firewall settings were causing the error, allowing the Java application should fix it.

Step 2: Check the Port

Another reason for the java.net.SocketException error is an incorrect port number. If the port number is incorrect, the socket will not be able to connect to the remote host. To fix this error, you need to check the port number and make sure it is correct.

Follow these steps:

  1. Open the Java application.
  2. Find the code that creates the socket.
  3. Check the port number in the code.
  4. Make sure the port number is correct.

If the port number was incorrect, correcting it should fix the error.

Step 3: Check the User Permissions

The java.net.SocketException error can also occur due to user permissions. If the user does not have the necessary permissions to connect to the remote host, the error may occur. To fix this error, you need to check the user permissions and make sure they are correct.

Follow these steps:

  1. Open the Command Prompt.
  2. Type "netsh winsock reset" and press Enter.
  3. Restart your computer.
  4. Open the Java application.
  5. Find the code that creates the socket.
  6. Check the user permissions in the code.
  7. Make sure the user has the necessary permissions.

If the user permissions were incorrect, correcting them should fix the error.
