Unstable connection from your device to our servers. A constant connection is necessary to keep the chat room updated in real time. This may be due to a slow network speed or weak WiFi signal/connection.
If you enable VPN/Tor/Privacy software after entering chat, you will be prohibited from using chat and you'll see the following message in the chat room: Error connection websocket error. Disable/turn off such services and then reconnect to chat.
