QuickBooks Not Connecting to Server After Update: Here’s What to Do

  

  1. If QuickBooks won’t connect to the server after an update, compatibility issues or network settings may be to blame. Start by verifying that your server is hosting the files correctly.

  2. Update the QuickBooks Database Server Manager and configure your firewall to allow server communication. Check for any bugs introduced in the update and use QuickBooks Tool Hub to troubleshoot.
