How do I fix a "no connection" error in MT4/MT5?
A “No Connection” message means your platform cannot connect to the trading server. Start by checking your internet connection, confirming your trading server and logging in again. Until the connection is restored, you cannot place, modify or close orders through the disconnected platform.
What happens to my trades while disconnected?
- Open positions: Remain on the trading server and continue to be exposed to market movements.
- Pending orders: Remain active under their applicable conditions.
- Modified Stop Loss and Take Profit: Remain on the server and can trigger under normal execution conditions.
- Manual trade management: Is unavailable through the disconnected platform.
A disconnection does not close your positions or protect them from losses or stop-out.
How do I restore the connection?
Follow these steps in order. The desktop menu paths below apply to MetaTrader 4 (MT4) and MetaTrader 5 (MT5):
Check your internet connection
Open a website in your browser.
If it does not load, reconnect to the internet and try again.
If websites load but the platform remains disconnected, continue below.
Confirm your login details and server
- Select File → Login to Trade Account.
- Enter your trading account number and trading account password.
- Select the exact server assigned to your account.
- Log in again.
Check your assigned server in the PU Prime Client Portal and your trading account credentials are correct.
MetaTrader 4 accounts must use MetaTrader 4, and MetaTrader 5 accounts must use MetaTrader 5.
Restart the platform
- Close the platform completely.
- Reopen it and check the connection status.
- If the error continues, restart your device.
Try another network
- Switch from Wi-Fi to a mobile hotspot or another trusted network.
- If available, try a wired internet connection.
- Corporate, school, hotel, or public networks may restrict trading-platform connections.
If another network works, the original network may be causing the issue.
Check VPN, proxy and security settings
- Temporarily disconnect your VPN or proxy and test again.
- Check whether your firewall or antivirus is blocking the platform.
- Allow the official MetaTrader application through your security software where required.
Avoid disabling your firewall or antivirus entirely.
Reinstall the platform if necessary
If the previous steps do not resolve the issue:
- Save any custom indicators, templates, or other local settings you need.
- Reinstall the platform using the installer from the PU Prime official website.
- Log in using your trading account details and assigned server.
Reinstallation does not remove your server-held trading account, balance, or open positions. Local files and settings may need to be restored.
What if the connection keeps dropping?
| What You Notice | What to Check |
| The connection drops repeatedly | Test another network or a wired connection for greater stability. |
| Your phone connects, but your computer does not | Check the computer’s network, firewall, VPN, and platform settings. |
| The platform shows “Invalid Account” | Recheck the account number, password, server, and platform version. This is a different error from “No Connection”. |
What should I do if I still cannot connect?

- Your trading account number and server name.

- Your device type and operating system.
- A screenshot or screen recording of the error.
