Remote Viewer: Multiple simultaneous sessions in different browser tabs not supported — use separate browser instances instead

Android

When opening Remote Viewer sessions in multiple browser tabs, each new tab disconnects the previous session, causing all tabs to display the same device instead of separate ones.

Why this happens

Remote Viewer uses a single WebSocket connection per browser instance. Every tab within the same browser shares that connection, so opening a second Remote Viewer session in a new tab forcibly terminates the first. This is an architectural constraint of WebSocket connections, not a defect.

How to view multiple devices simultaneously

1. Close any existing Remote Viewer sessions in your current browser to start from a clean state.
2. Open a second independent browser instance using one of these methods:
   • Launch a different browser application (for example, open Microsoft Edge alongside Google Chrome)
   • Open a new Chrome window under a different Chrome profile — each profile maintains its own separate WebSocket connection
3. Navigate in your first browser instance to Devices & Groups → [First Device Name] → Remote Viewer and start the session.
4. Navigate in your second browser instance to Devices & Groups → [Second Device Name] → Remote Viewer and start the session for the other device.

Verify: Each browser instance should display its own independent device stream without interrupting or redirecting to the other. Neither instance should show an active session in another tab warning. Streams should remain stable as long as both browser instances stay open.

If this doesn't resolve it

If sessions are still disconnecting across separate browser instances, collect the following before contacting Esper Support:

• Browser names and version numbers for each instance in use
• Screenshots or screen recordings showing the disconnection behavior
• The device names or serial numbers involved
• Any error messages or codes displayed during the session
