How to fix the connection failure between PyCharm and the remote server?

If PyCharm fails to connect to a remote server, you can try the following troubleshooting methods:

1. Check the connection settings of the remote server to ensure the correct host name, port number, username, and password are entered.
2. Ensure that the SSH service is installed and running on the remote server.
3. Make sure that OpenSSH or other necessary SSH client tools are installed on the local computer.
4. Check the firewall settings to ensure that communication between the local computer and the remote server is not being blocked.
5. Try using a different SSH client (such as PuTTY) to connect to the remote server to confirm if it is a PyCharm issue.
6. Updating PyCharm to the latest version may resolve known connectivity issues.
7. If the above methods are not effective, you can try resetting the connection settings or contacting PyCharm’s technical support team for assistance.
