First confirm live chat is on for the site and the current domain is allowed. Install details are in Install & enable.

What you see	Check first
No bubble	The switch was saved and the page reloaded. The script tag does not say data-chat="false". The current domain is on the allowed list. A narrow window or a phone browser may be hidden by Hide bubble on mobile. The network panel should show same-origin w-chat.js
The bubble works but the inbox never gets the message	When the quota is used up and overage billing is off, a new visitor only sees the message form. See Billing & quotas
No sound	The inbox sound toggle may be off. A muted tab, or a browser that has not been allowed to show notifications, leaves a badge and no sound. That prompt is a browser notification, not a separate push app to install
Translation does nothing	Free has no automatic translation. The switch is Two-way auto translation on Greeting & translation. If the platform has no AI, or translation does not finish within about 3 seconds, the original is sent and the inbox says it failed. See Two-way translation
It says disconnected	The visitor window and the inbox both reconnect on their own, waiting longer each time: up to about 15 seconds for the visitor window and about 10 for the inbox. Send again after it returns. The open conversation is still there
You are online but visitors see offline	Outside office hours the bubble uses the offline greeting even if an agent marked themselves online. Inside hours someone must be Online. Away and offline do not count. See Hours & offline
The agent side stays on connecting	Check whether the member is a Viewer. Viewers cannot use live chat. If a reload does not help, check whether the browser blocks the chat gateway

A strict content security policy can block the script, the gateway connection, or the page inside the chat window. See CSP, blockers & networks.
