If you need help, use the support channels provided in your client area. Include enough detail to make troubleshooting possible on the first pass: the server name or service ID, the affected IP or hostname, the approximate time of the issue, and any error messages you are seeing.
The more specific your report is, the faster the issue is usually resolved. Vague reports such as 'it does not work' slow everything down.
Before opening a ticket, gather logs or exact symptoms if you can.
