The first viable solution in the ambit of the troubleshooting instructions is that you update QuickBooks Desktop to the most recent Version.

• For this purpose, you are required to opt for the "Run as Administrator" option after right-clicking the QuickBooks icon.
• You are required to tap the "Ctrl" key on the keyboard while launching QuickBooks. The No Company Open screen comes when you hit the Ctrl key to open QuickBooks.

Solution 2: Alter Permissions related to Company File Folder
The ability to transfer files across the network should be granted to the company file folder.
To configure the folder permissions correctly, adhere to the directions below:
• Locate the company file's folder and perform a right-click on it.
• Next, opt for "Security" under "Properties."
• Choose "QBDataServiceUserXX" by clicking "Edit."

Solution 3: QuickBooks Tool Hub can fix the issue
Download the QuickBooks Tool Hub from the official Intuit website, then launch the QuickBooks File Doctor Tool. It will correct typical company file issues in the QuickBooks Desktop and run a mini-repair on your firewall and server. Do not open the company file in QuickBooks again until the troubleshooting is finished. If QuickBooks is still unable to access the company file on the server, move on to the next solution.
Solution 4: Examine the Firewall Settings
Intuit does not govern anti-virus and firewall software. QuickBooks must be manually excluded from Firewall settings. Your firewall can be preventing QuickBooks from establishing a connection to the servers. Include QuickBooks in the list of Firewall security exclusions to determine if the issue has been resolved. If the issue with QuickBooks Cannot Communicate with the Company File is still present, move on to the next option.
Solution 5: QuickBooks Database Server Manager should run On Server PC
On a server computer, which is different from other devices known as workstations, is where your QuickBooks company file is kept.
• Verify QuickBooks Tool Hub is set up on the server computer, then hit on "Network Issues."
• Choose QuickBooks Database Server Manager once more.
• Afterward, opt for "Start Scan" in the QuickBooks Database Server Manager to search for any files or folders that may be visible. Otherwise, move to the destination containing the company file.
• Once the Scan is complete, wait for QBDBMgrN to automatically fix the firewall permission problems.
• Having performed all the instructions, see if the communication issues with the Company File have been resolved.
Solution 6: Only Host PC must have Multi-User Access Enabled
The Host Multi-User Access setting on the workstations needs to be disabled. Only the system that hosts your QuickBooks company file is capable of hosting it.
• Start off by launching QuickBooks on your computer.
• Instead of opening company files, choose the "File" menu and then hit on the "Utilities" option.
• If the option to "stop hosting multi-user access" is available, choose it.
• If the Host Multi-User Access option is present, proceed to the following workstation and repeat the procedure.
