Debugging server warning

Overview

If you see the following warning message on your dashboard:

Server Warning banner

(Server Warning - No communication for at least 20 minutes)

…please follow the guide below to try to determine the cause and the suggested next steps.

What does the error mean?

If the Cloud 66 agent on a server is not able to ping Cloud 66 for 20 minutes, we will display the Server Warning notice on the dashboard and on the individual server detail page. (We will also notify you directly via your chosen channels.)

Why has my Server lost Communication with Cloud 66?

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

Is the Server Down?

Is the server unresponsive due to high load?

This can happen if your server is overloaded. To determine if this is the case, SSH to the server and run the top or htop commands.

This will show you which processes are running and how much memory and CPU is being 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.

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 (see below).
