Miro Connection Lost / Changes Not Saving
Quick answer
Reconnecting messages and lost edits come from dropped WebSocket connections. Refresh before you continue, avoid closing the tab right after editing, and recover with Ctrl/Cmd+Z or board history.
Most likely fix: Stabilise the connection
How to fix it
Try these in order — the most common fix is first.
1. Stabilise the connection
- Switch off VPN or proxy and test on a different network
- Use a wired or stronger Wi-Fi connection
- Keep the tab active while editing
- Refresh the tab if you see a reconnecting message after being away

- Copy long text elsewhere before editing it in Miro
- Export a backup of critical boards

- Press Ctrl/Cmd+Z right after reconnecting; users recovered deleted branches this way
- Open board history if your plan includes it
- Contact Support with the board link and the approximate time of the loss

- Duplicate the board and check if the error follows the content
- Try another browser or the desktop app

Symptoms
A 'reconnecting' or 'connection restored' banner appears, typed text vanishes after a reload, or the board refreshes itself.
Why it happens
- Unstable network, VPN or firewall blocking WebSockets
- Background tab sleeping and reconnecting
- Unsynced edits overwritten when the connection returns
- Rare Miro-side bugs after releases
