Solutions to Fix QuickBooks Error H505

Now, let’s move to the solutions for QB error code H505:

Ensure that the “Host Multi-User Access” option is turned off on your workstations. Workstations should not host your company files; this should be done only on the server computer.

Note that you can perform these steps before opening a company file.

On any workstation displaying H101H303, or H505 errors:

  1. Open QuickBooks.
  2. Avoid opening your company file.
  3. Instead, click on “File” and then choose “Utilities.”
  4. If you get the “Host Multi-User Access” option, do not select it. Move to the next workstation, as this is not causing the issue.
  5. If you witness the option “Stop Hosting Multi-User Access,” select it.
  6. Replicate these steps on all workstations where you encounter Error H101, H303, or H505.

After checking your workstations, move to your server computer, which is the usual host of your company files:

  1. Open QuickBooks on your server computer.
  2. Select “File,” and then choose “Utilities.”
  3. If you see the button “Host Multi-User Access,” select it. Do not select “Stop Hosting Multi-User Access” if it is available.

Solution 2: Test your Network Connectivity

Run a ping test on your server computer to ensure a proper connection between the server and workstation computers. Test the IP address connection as follows:

  9. Follow the same steps on each workstation that is giving you the error code H505.
  10. If some workstations can’t receive all the packets sent to the server, contact your IT team for further troubleshooting assistance.
