# Trading GUI Troubleshooting
Updated: `2026-04-01T16:45:07Z`
## Root Page Shows `Stopped`
- this is normal safe default behavior
- click `Open MT5 GUI`
- unlock the session
- wait for the protected page to request session start
## Root Page Shows `Starting` For Too Long
- click `Refresh Status`
- open `https://trading.bizniz.cloud/logs/summary`
- check `mt5-browser-session.service` and `mt5-browser-gateway.service`
## Unlock Succeeds But Preview Does Not Appear
- click `Refresh Status`
- if needed, click `Start Session`
- verify the protected page eventually shows `Running`
- if it still fails, check browser-session logs
## Snapshot Route Returns Unavailable
- the session stack is likely inactive or still warming up
- refresh once
- if still unavailable, open the log summary and verify the browser session services
## Embedded GUI Looks Blank
- open the MT5 client in a new tab from the protected session page
- refresh once after the browser session turns `Running`
- confirm the session stack is not back in `Stopped`
## Start Or Stop Action Fails
Check:
```bash
systemctl status mt5-browser-session.service mt5-browser-gateway.service --no-pager -l
/trading/forex-mt5/scripts/status-browser-session-stack.sh
tail -n 80 /trading/forex-mt5/logs/browser-session/mt5-browser-session.log
tail -n 80 /trading/forex-mt5/logs/browser-session/x11vnc.log
```
## Security Reminder
- do not bypass the protected session route
- do not publish raw VNC, RDP, or X11
- do not enable live trading while troubleshooting
