🔍 The Technical Reality Behind the Error
When your Multi-User Mode connection fails, the issue is usually:
👉 Database Server Manager Handshake Failure

This mismatch causes:
Connection interruption during multi-user access
Company file hosting failure
Network path verification errors
Endless "Connecting to Server" loops

55378-55382 (Additional QuickBooks ports)
Click Allow the connection → Apply → OK
This resolves most QuickBooks Desktop network connection error support cases.

👉 Steps:
Open QuickBooks Database Server Manager
(Example: Start Menu → QuickBooks → Database Server Manager)
Locate tab:
👉 Scan Folders
Remove existing company file folder
👉 Re-add the folder containing your .QBW file
Click Scan → Wait for completion
