Good evening, @missmissySEI

 

It's great to see you back in the Community! 

 

Some of the possible reasons for connection error are the following:

 

  • Windows firewall and other internet settings are blocking the QuickBooks file to access the required ports.
  • The Network Descriptor (ND) file is missing or corrupted.
  • The hosting computer is in standby or hibernation mode. This may interrupt your connection due to which you cannot access the company files.
  • Your server connection is interrupted.
  • QuickBooks installation files are corrupted.
  • Multiple QuickBooks database service windows are in use.
  • Your QuickBooks company files are damage

 

To get that resolved, you can download and run our QuickBooks Desktop (QBDT) Tool Hub. This tool help fix problems and errors in QBDT. Here's how: 

 

  1. Close QuickBooks.
  2. Download the QuickBooks Tool Hub. Then, save it on your Desktop.
  3. Open the file you downloaded (QuickBooksToolHub.exe). Follow the on-screen steps to install and agree to the terms and conditions.
  4. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
  5. From the launch pad, click Network Issues.
