• Use tools like netstat or lsof to confirm that no other service is using the port.

Connection Refused Errors

Problem:

Connection attempts are met with refusal.

Solution:

• Ensure the service is operational and configured to listen on “127.0.0.1:62893.”
• Check firewall settings to ensure they allow traffic on this port.
• Restart the service and review configuration files.

Address Already in Use

Problem: Port 62893 is occupied by another service.

Solution:

• Terminate the conflicting service or choose an alternative port.
• Confirm that no other applications are utilizing the port.

Latency and Performance Issues

Problem: Experiencing delays or sluggish performance.

Solution:

• Investigate for any resource-heavy processes running on the machine.
• Optimize the code for better performance and resource management.
• Ensure background services are not affecting network performance.

Conclusion
