What To Do When stuck in QuickBooks Error H505 After new update?

Copper Contributor

I'm encountering QuickBooks Error H505 when trying to switch to multi-user mode. The error message indicates that my company file is on another computer, but it can't communicate with it. What steps can I take to resolve this issue and ensure QuickBooks runs smoothly in multi-user mode?

QuickBooks Error H505 indicates issues with multi-user hosting setup. Troubleshoot by verifying hosting settings, firewall configurations, and DNS settings. Utilize QuickBooks Connection Diagnostic Tool to identify and fix network-related problems for seamless multi-user access.
