Methods to Fix QuickBooks Error H505 include the following:

We gathered a number of fixes and verified them by running them through the system. You can certainly go with any of the options listed below. Otherwise, you might look for a solution based on the problem’s root cause.

It will be a plus if you have found out the likely cause of the problem.

Solution 1: Make a new folder for your company.

This is most likely the most straightforward answer to the problem. You can either create a new folder to eliminate the error, place it in the business folder. If you’ve never created a new company folder before, follow the procedures.

On your hosting system, create a substitute folder. Now, copy the original folder to the replacement location and provide Windows access to it.

  • When you don’t have access, you can hire a professional.
  • Using multi-user mode, copy the qbw file into the new folder.
  • Check to see if you can now open the company files.

Solution 2: Changing the Network Port Settings on Your Computer

When working with QuickBooks services, you can check to see if everything is in order on your system. This solution has been broken into three pieces so that you can take care of each and every application configuration.

 Firewall Configuration

Perhaps Windows Defender, Firewall, the built-in defender of Windows, is preventing you from opening the file. To fix the problem, you should adjust the Windows Defender Firewall settings.

  • Using your system’s search box, look for Windows Firewall. Then, from the search results, select Windows Firewall and select the advanced option from the current window.
  • Select Outbound Rules from the left pane and right-click. Select a New Rule.
  • Select next from the Ports menu.
  • The TCP should be selected.
  • Select Next and then “Allow the Connection.”
  • To fill up the name area, click Next one more, then Finish.
  • To update the inbound rules, perform steps 1 through 5 once more.

Check if the error still occurs in QuickBooks’ multi-user mode.

 Turning on the Network Discovery

After you’ve adjusted the firewall’s settings, make sure you enable this option. The issue may still be present in your system if you omit this step.

  • Using the Start menu, go to your system’s Control Panel. Go to the Security and System section.
  • Select Windows Firewall from the drop-down menu.
  • Select “Allow associated app/feature to run on the Windows Firewall” and hit it.
  • Select Modification from the drop-down menu.
  • Select Network Discovery and then click OK.

Know the Name of the Server

This procedure will assist us in solving the next problem. However, because it is related to the system’s network, we shall discuss it here.

  • To open the Run dialogue box, press and hold Win+R. Type cmd into the box and press Enter.
  • Enter “config/all” as a command.
  • In the IP area, look for the Host Name. Right next to the Host Name is where you’ll see the Server name. Save your work and move on to the next step.

Solution 3: Keep an eye on the hosting and service providers.

Ascertain that the hosting and services are in working order. To use Quickbooks on your system, you’ll need to keep your hosting and services up to date.

Check the Hosting

On each workstation, you must check the hosting. You won’t have to bother with the hosting PC or server this time.

  • On each workstation, open QuickBooks.
  • Afterwards select Files, after these Utilities.
  • If multi-user mode appears in the list, your machine is most likely not hosting that company file.
  • You must move to the next machine if you observe multi-user access on a workstation. Make no changes in this area.
  • Select “Stop Hosting the Multi-user Access” from the drop-down menu. For each computer, follow the same instructions.

Check the Services

You must now confirm that QuickBooks services are operating on your system. You can examine your system’s service list. To complete the process, follow the below steps.

  • To open the Run dialogue box, press and hold Win+R. In the search bar, type “services.msc.”
  • In the service window, look for QuickBooks DBXX services. Double-click it to activate it.
  • To get started, go to the Recovery tab. If you find any errors, manually launch Quickbooks.
  • To save the changes, select OK.

The steps from 2 to 4 must be repeated for QBFC Monitor services.

Open QuickBooks on the PCs that are affected now. If you are able to open the file, the problem has been fixed. If not, you’ll need to construct QuickBook DBXX with the appropriate admin access and permissions to fix the problem.

Fix 4: Make a change to the Windows Host File

From Fix 2, you still know the server and host name. Now, we’ll put them to work in this solution to get rid of the QuickBooks error code H505. Make a note of the host and server information.

  • Go to the Start menu after quitting QuickBooks.
  • “C:WindowsSystem32DriversEtc” or “C:WindowsSystem64DriversEtc” are the correct paths to take.
  • Fill in the IP address and computer name after opening the file.
  • Save the file with the changes.

Check if you can open the specific company file by restarting QuickBooks in multi-user mode.
