Step 3 : Check your internet connection

While the QuickBooks Connection Diagnostic tool can fix a vast majority of network related errors, it cannot actually fix the internet issues caused because of security software or because of internet issues. So at this point you should definitely check your internet connection and contact your internet service provider if the connection isn't working properly. 

You may also have to check Firewall settings to ensure that QuickBooks desktop can actually access a company file that is stored on a different system or server. This is quite common for users who have hosted their company file on a separate server in order to activate multi-user mode in QuickBooks desktop.

Step 4: Check for company file errors

Even if you get a network related issue, the real problem may lie with the program files or the company files. In such cases, you need to scan for both types of errors and eliminate the underlying causes.
