MT5 troubleshooting
The failures that actually happen, and what each one means.
| Symptom | Most likely cause | Action |
|---|---|---|
| Expert not in Navigator | File placed in the wrong folder, or terminal not restarted | Re-open the data folder and restart MetaTrader 5 |
| Authorisation refused | Account, server or device does not match the binding | Compare the values in Account → MT5 accounts |
| Request blocked | WebRequest permission missing | Add the endpoint under Tools → Options → Expert Advisors |
| Intermittent disconnects | IP changed, or a VPN is rotating exits | Use a stable connection, then re-check the License |
| Works on one machine only | Device limit reached | Review device slots in Account → Licenses |
| Analysis unavailable | Service degraded upstream | Retry later; nothing is executed on a stale result |
