We cannot know what might have caused an error
while working with QuickBooks. It can be because
of a single thing or a combination of various
factors. But one crucial thing in this is to keep
a calm mind while solving the error, as we don't
want to trigger another error while resolving the
current one. In the H series, the error is
generally triggered when the user tries to access
the company file or other data from another
computer and that system is not configured
correctly for the hosting setting.    So, when
the QuickBooks Error Code h505 occurs, it
displays the following message "This company
file is on another computer, and QuickBooks needs
some help connecting."
The reason behind QuickBooks error H505 triggers
is when the user tries switching to the
multi-user mode. So it's safe to say that
something is blocking the multi-user connection
between you and your server, which is generally a
misconfiguration of the hosting system.
