Error #0223: server connection was lost

 

Error description

An emergency disconnection of a network connection via HTTP protocol in any MyChat WEB service (Admin panel, Kanban board, forum, WEB chat...).

 

Problem solution

  1. Make sure, that your MyChat Server is working. This error occurs when you switch off a computer with MyChat server, or MyChat Server service/application end its work.
     
  2. Make sure, that  disconnection does not deal with a network equipment and there is no connection failure.To do this, run the command ping -t <ip_server>, for example:
    ping -t mychat-server.com

    There must be no package losses.
     
  3. Check the settings of your antiviruses and firewalls. MyChat WEB services work based on WebSockets technology; a lot of antiviruses block HTTP traffic and "brake" packages, and cause disconnections.
     
    The problem can be solved by adding the IP address/DNS name of your MyChat Server to antivirus/firewall exclusion list, or by enabling HTTPS (encryption certificates are required).
