What are the reasons for QuickBooks error H505?

The QuickBooks error H505 appears on the screen because one or more of the user’s computers are configured to serve as the QuickBooks server. Normally a user’s computer can only function in the multi-user mode, while the computer that hosts the company file can only function as the server computer or can act as the host. So if this condition does not follow, you may face the QuickBooks Error code H505. The other reasons for the error H505 are as follows:

  • The QB server is unreachable or down: 

When the server you want to establish a connection with in order to access a company is unreachable or down, this can also cause an error message. In such a scenario, you should check the server and ensure it is up and running before connecting again. 

  • If the multiple workstations are hosting multi-user connections:

When the multiple workstations in the network act as the server, the QuickBooks error code H505 can appear on the screen. This can happen when the Host Multi-User Access option is enabled on the other computers instead of the server one. To fix this, you will have to disable the option of hosting multi-user access on every workstation other than the server.

  • When the Windows Defender Firewall blocks the connection:

When the Windows Firewall application on your device does not allow you to establish a connection with the server, the error H505 may appear on your screen. If you are stuck in the same case, then you have to allow QuickBooks to pass through the firewall manually. You can also set up a new rule to configure Windows Firewall such that it allows the use of specific ports for QuickBook.

  • If the QuickBook services are not running on the server:

The QB application uses some specific servers to facilitate the connections between itself and other workstations on the network. So if the services are not running smoothly in the background while you try to access the company file on the server, it can trigger the QuickBooks error H505. Therefore, you should ensure that the services run smoothly in the background before proceeding ahead.

  • If the Quickbooks Database server is not able to scan the QuickBooks files/folders:

The database server scans the QB file before connecting any workstation in the multi-user mode. So, if there is some issue and the QB database server is not able to scan the files, it will show the error code H505.

If your QuickBooks Database Manager is not working then you may see QuickBooks Error 100, know how to solve QuickBooks Error 100.

  • If you have a damaged or missed Network data file.

The Network data file (with .ND extension) allows the Qb Desktop to access the company file in a network or the multi-user environment. Any corruption or damage in this .nd file can also lead to QuickBooks error code H505.

  • If QuickBooks can not trace the IP address of the computers, it can reflect the QB error H505.
  • If the DNS settings on your system are not configured accordingly, you can face the QB error code H505.
