Fixes for QuickBooks Connection Has Been Lost" Error
Perform the following fixes to get rid of this error once and for all.
Check the internet connectivity
One pre-requisite before opening the company file is to ensure a seamless internet connection. Unstable net connection or interruptions in the network can straightaway result in the connection errors. So you need to start up your computer, modem/router and then get online. Switch between Wifi and ethernet to ensure your net is stable.
Cross-check firewall and antivirus software
If the firewall is too restrictive, the anti-virus program can block access to QuickBooks company files. Disable the firewall and antivirus to test if that can cause any conflict. You can even configure them to let connections on ports QuickBooks uses. Enable the ports:
- 8019 for QuickBooks desktop
- 443 for QuickBooks online
If connection issues are gone after disabling firewalls, you must adjust configurations to allow QuickBooks access.
Update QuickBooks software
An out-of-date version of QuickBooks can show errors. So, update the program by opening the Help tab then choose the option to Update QuickBooks Desktop. You can also update QuickBooks automatically by setting the automatic updates on. Always keep the software updated to prevent interference by any technical bugs.
Try switching between multi-user and single-user mode
Users can switch between single-user and multi-user modes. This is possible by opting for the File menu then click on Switch to single-user mode. If the connectivity error gets fixed by doing this, it infers some technical problem with multi-user connectivity settings. These can be fixed by using the QuickBooks File Doctor in the QuickBooks Tool Hub.
