Last updated May 7, 2024
Introduction:
Encountering connection issues while managing remote servers can be frustrating, but understanding common causes and troubleshooting steps can help resolve issues quickly and get you back to work. In this guide, we'll cover some common connection issues that users may encounter in Termius and provide step-by-step troubleshooting solutions to help diagnose and resolve these issues effectively.
Troubleshooting Connection Issues:
- Check Network Connectivity:
- Ensure that your device has an active internet connection by visiting other websites or applications.
- Verify that the remote server you're trying to connect to is accessible from your network and not experiencing any downtime or network issues.
- Verify Server Credentials:
- Double-check the hostname or IP address, port number, username, and password or SSH key used for authentication.
- Ensure that the credentials entered are correct and match the authentication requirements set up on the remote server.
- Review Firewall and Security Settings:
- Check firewall settings on your local device and network to ensure that they're not blocking outgoing connections to the remote server's port.
- If using SSH key authentication, verify that the correct public key is added to the remote server's authorized_keys file and that SSH key authentication is enabled.
- Update Termius and Dependencies:
- Ensure that you're using the latest version of Termius and that all dependencies and system packages required for SSH connections are up to date.
- Update Termius to the latest version available on your platform's app store or package manager to fix any known bugs or compatibility issues.
- Verify Server Availability and Response:
- Use ping or traceroute commands to check the availability and responsiveness of the remote server.
- If the server is unresponsive or unreachable, contact the server administrator or hosting provider for assistance.
- Check SSH Configuration on Server:
- Review the SSH server configuration file (/etc/ssh/sshd_config) on the remote server for any misconfigurations or restrictions that may prevent connections.
- Look for settings such as AllowUsers, AllowGroups, PermitRootLogin, and PasswordAuthentication to ensure that they're configured correctly.
- Enable SSH Debugging:
- Enable verbose logging and debugging output in Termius to gather more information about connection attempts and errors.
- Review the debug logs for any error messages or warning signs that may indicate the cause of the connection issue.
- Try Alternate Connection Methods:
- If you're unable to establish an SSH connection, try connecting using alternative methods such as Telnet or HTTP tunneling (if supported by the remote server) to troubleshoot connectivity issues.
- Contact Support for Assistance:
- If you've exhausted all troubleshooting steps and are still unable to resolve the connection issue, contact the Termius support team for further assistance.
- Provide detailed information about the issue, including error messages, debug logs, and steps taken to troubleshoot, to help expedite the resolution process.
