Suddenly kicked out from my EC2 instance

Question

Hello, its my first time asking something here. To work on my EC2 Instance I use VSCode to connect via SSH with the "Remote-SSH" plugin. I have been working on this instance with no problem for 1 weeks with occasional disconnections, but I really want to fix this error.

I have tried to turn off all firewalls. Im sorry to not have any more information, but it literally happen while i code so i have no idea what could have cause it.

Accepted Answer

If you're experiencing occasional disconnections while using VSCode with the Remote-SSH plugin to connect to your EC2 instance, there could be several possible causes.

Here are some troubleshooting steps you can try:

1. Check your network connectivity: Make sure your local network connection is stable and strong. You can also try pinging the EC2 instance from your local machine to check if there are any network issues.

2. Check the system logs: Check the system logs on the EC2 instance to see if there are any error messages or warnings related to SSH or network connectivity.

3. Check the SSH daemon logs: Check the logs of the SSH daemon (/var/log/auth.log on Ubuntu, for example) on the EC2 instance to see if there are any error messages related to SSH authentication or connectivity.

4. Increase the SSH timeout: You can try increasing the SSH timeout value in your VSCode Remote-SSH settings. To do this, go to the VSCode settings and search for "remote.SSH.timeout". Then, set the value to a higher number, such as 60.

5. Enable SSH keepalive: You can also try enabling the SSH keepalive feature to prevent disconnections due to inactivity. To do this, add the following lines to your SSH configuration file (~/.ssh/config on your local machine):

```
Host *
    ServerAliveInterval 60
```

This will send a keepalive message to the SSH server every 60 seconds to prevent the connection from timing out.

6. Check for any resource limitations: If your EC2 instance is running low on resources, such as memory or CPU, it could cause disconnections. Check the system logs on the EC2 instance for any error messages related to resource limitations.

7. Try a different SSH client: If none of the above steps work, you can try using a different SSH client, such as PuTTY, to connect to your EC2 instance.

I hope these steps help you resolve the issue. If you're still experiencing problems, feel free to provide more information about the error message or any additional details that could help diagnose the problem.
