When troubleshooting issues with Telnet connectivity or authentication, follow these steps:

1. Check your network connection to ensure that you have a stable internet connection.
2. Verify that the Telnet service is running on both the client and server machines.
3. Ensure that the Telnet port (usually port 23) is not blocked by firewalls or antivirus software.
4. Check the Telnet configuration files for any errors or misconfigurations.
5. Verify that the username and password entered for authentication are correct.
6. Test the Telnet connection using a different Telnet client to see if the issue is client-specific.
