On 15 October 2018, MYOB made a security change which may result in a 4001 error if you're using Windows 7. But it's easily fixed - see AccountRight Classic TLS security change for details.
If you're getting a "4001" connection error when using M-Powered services, it means your computer can't connect to our server. To fix this, try changing your internet settings as shown below.
In Windows 8 and later: Right-click in the bottom-left of the screen and choose Control Panel.
In earlier Windows versions: Click the Windows Start button and choose Control Panel.
Click Internet Options.
Click the Connections tab.
Click LAN settings.
Deselect the option Automatically detect settings.
Click OK.
Click OK on the Internet Properties window.
You'll now be able to successfully complete a Send\Receive in your M-Powered Service Centre.
If the issue persists
This error can also be caused by your firewall or antivirus software preventing the connection. Try temporarily disabling these programs to see if they're causing your issue. If the issue is resolved by disabling these programs, you'll need to modify your firewall or antivirus program to ensure they don't interfere with the M-Powered connection (port 443 needs to be "open"). You might need an IT person to help with this. Also see M-Powered Common Connection Errors (Australia only).
