I see the "Server Warning - No communication for at least 20 minutes" message. What should I do?

On the dashboard and server detail page, I can see the warning message:

Server Warning - No communication for at least 20 minutes.

What does this mean and What action should I take?

In the event that Cloud 66 is not able to communicate with one of your servers for 20 minutes it will display the Server Warning notice on the dashboard and on the individual server detail page.

Why has my Server lost Communication with Cloud 66?

This may happen for a number of reasons. Let’s explore some of the common scenarios
and describe how you might troubleshoot this problem and determine what action you should take.

Is the Server Down?

  • Can you visit your website? — Does it respond in your browser as you would expect? Try to browse it by both web address and IP of the server (IP is available in the server detail page of the Cloud 66 Dashboard). If your site is now responding there may have been an intermittent connectivity issue that will resolve itself and the notification will be removed.

  • Has the server been shut down or paused? — Check your Cloud Provider dashboard for details. Make sure the server is running. You can also try rebooting the server. Does this resolve the issue?

  • Can you connect to your server via SSH? — If you are unable to connect double check the dashboard of your cloud provider and try to determine if the server is definately running. If you can connect try running htop as described below.

Is the Server unresponsive due to high memory or CPU load?

This can happen if your server is overloaded. How do I determine if this is the case? SSH to the server and run the top or htop commands.

This will show you what processes are running and how much memory and CPU is utilized. If you see excessive load, reboot the server via your Cloud Provider dashboard.

If the server is consistently coming under high load you should investigate upgrading it or scaling your application to use more servers.

Are there any Network Connectivity Problems?

It may be possible that there is either an intermittent or persistent network connectivity issue.

  • See if you can ping your server — This will help to determine if there are any network connectivity issues.ping yourdomain.com Is there any packet loss?

  • Run traceroute — Try running the traceroute command.

If you see connectivity problems you should check your cloud provider and see if there are any network issues. Please check the status page of your cloud provider.

Is your Cloud Provider Down?

Occasionally your service provider may have problems. You can check this by visiting the status page of your Cloud Provider:

This may occasionally happen due to site maintenance. Please check the service status pages:

I have none of these problems, but I still see this message

If you have ruled out the issues described above, and still see the notification please contact support. There may be an issue with the Cloud 66 Agent software on the server.
