The "ℚ𝔹 cannot communicate with the company file" error occurs when ℚ𝔹 fails to connect to the file stored on a server or another system. This issue is often caused by network connectivity problems, incorrect hosting settings, or firewall restrictions.

Steps to Fix the Issue:
Check Network Connection – Ensure both the server and workstation are connected to the same network.
Run ℚ𝔹 Database Server Manager – Open ℚ𝔹 Tool Hub > Network Issues > Run Database Server Manager to scan for connection problems.
Verify Hosting Settings – On the server, go to File > Utilities > Host Multi-User Access and make sure only the host system has hosting enabled.
Adjust Firewall and Security Settings – Add ℚ𝔹 to firewall exceptions to prevent security software from blocking communication.
Restart ℚ𝔹 – Open Run (Windows + R) > Type "services.msc" > Find and restart the service.
