Our EAs need to connect to our servers to validate license. This guideline is provided if you are experiencing “no license” error while you have a valid license. In such cases, please try the following common troubleshooting steps.
1. Make sure FRZ server is correctly added under allowed URLs
- Open MetaTrader. Go to Tools → Options → Expert Advisors.
- Make sure “Allow WebRequest for listed URL” is checked.
- Copy-paste this URL to the list: https://frzserver.com (copy-paste the URL to avoid any typos. Also make sure there are no leading/ending spaces) and then click OK.
It should looks like below:
2. Check MT4 Proxy Settings:
- Go to Tools > Options > Server in MT4. If a proxy is configured, ensure it allows outbound HTTPS requests to frzserver.com. Test with no proxy (set to “No proxy”) if possible.
3. Try a different Wi-Fi or use a mobile hotspot
If possible, try a different Wi-Fi or use a mobile hotspot and see if the issue is solved.
4. Try a different PC or VPS
If possible, try a different PC or VPS, and see if the issue is solved.
5. Make sure your MT4/5 is the latest version
How to Update MetaTrader Automatically
- Close MetaTrader.
- Right-click on the MetaTrader shortcut and select “Run as administrator.”
- If an update is available, MetaTrader will download and install it automatically.
- Re-open MetaTrader and check the build number again
6. Make sure Antivirus/Firewall does not block FRZ Server
- WebRequest() blocked – Add MetaTrader to allowed applications in your firewall.
- Overprotective antivirus (e.g., Kaspersky, Norton) – Temporarily disable antivirus to test if it is blocking the license check.
Whitelist terminal.exe and frzserver.com in your antivirus/firewall settings:
1. Whitelist terminal.exe (MetaTrader) in Windows Defender
If you’re using Windows Defender, follow these steps: Start → search for “Windows Security” → open it.
2. Go to:
Virus & threat protection → under “Virus & threat protection settings”, click “Manage settings”.
3. Scroll to “Exclusions” → click “Add or remove exclusions”.
4. Click “+ Add an exclusion” → choose File.
5. Navigate to your MetaTrader installation folder:
Example path: C:\Users\<YourName>\AppData\Roaming\MetaQuotes\Terminal\<LongHexCode>\terminal.exe
6. Select terminal.exe.
Whitelist Domain frzserver.com in Windows Defender Firewall
Open Control Panel → System and Security → Windows Defender Firewall.
On the left, click “Advanced settings”.
Under Outbound Rules, click New Rule…
Choose the following:
- Rule Type: Custom
- Program: Select path to terminal.exe
- Protocol and Ports: Leave as default (any)
- Scope: Add frzserver.com or 74.208.82.41 (if IP needed)
- Action: Allow the connection
- Profile: All
- Name: Allow MetaTrader to frzserver.com
If You Use 3rd Party Antivirus/Firewall (e.g., Kaspersky, Bitdefender, ESET)
Look for these settings:
Exclusions / Exceptions → Add:
- File: terminal.exe
- Domain or IP: frzserver.com and/or 74.208.82.41
Web/Internet Protection:
- Disable SSL scanning temporarily.
- Add frzserver.com under trusted sites.
7. Windows 7 users – Make sure you have KB3140245 update
Windows 7 users: Install all Windows Updates Specifically: KB3140245 enables TLS 1.1/1.2 in WinHTTP (used by WebRequest) and enable TLS 1.2 support.
