Cause
Starting with Chrome 142 and Edge 143, both browsers introduced a new security feature called Local Network Access (LNA). This feature blocks websites from connecting to local or internal network resources by default.
Because the OnBase Integration relies on a secure connection to Pomona’s internal OnBase API server, the new browser policy prevents the integration from loading unless the Local Network Access check is disabled.
