Common causes include:
Incorrect firewall settings
QuickBooks not added as an exception
Network ports required by QuickBooks are blocked
Third-party antivirus interference
Whether you're facing issues with QuickBooks Payroll, QuickBooks Premier Plus, or QuickBooks Enterprise, the firewall may block necessary files and services that QuickBooks needs to function properly.

Error codes like H202, H505, or 6000 series
Inability to open a company file located on another computer
Multi-user mode not working
