QuickBooks Error H202 happens when a multi-user setup is unable to establish a connection to the company file that is off-site. It is frequently brought on by blocked server communication, incorrectly configured hosting settings, or network problems. Using the QuickBooks Database Server Manager, confirming hosting settings, and upgrading firewall permissions are the steps involved in fixing it.
