Not Able to Update QuickBooks Over VPN

Not Able to Update QuickBooks Over VPN

Let’s discuss the VPN connection and its precise meaning. You can connect to a business network from your home using a virtual private network, or VPN. Having said that, you claimed that using the VPN prevented you from accessing QuickBooks. Are you certain that you are using the correct VPN?

If you’re connected to the right VPN, could we suggest a solution for you to try here?

Why can’t I use a VPN to access QuickBooks Desktop?

Due to bandwidth and file size restrictions, the majority of applications with databases or corporate data files do not function well with VPN. I’d advise getting in touch with your IT department to get advice on the best connection configuration for accessing your QuickBooks Desktop.

Resolution to fix Not Able to Update QuickBooks Over VPN 

The message “No company file can be found” is what you claimed to be receiving. Let’s return to the fundamentals by connecting to and opening a company file for the first time.

The company file may have been moved or the network may have been down when this happened. You should find the company file and then sign in to it so that you can remember where it is again.

1. Select “Open or restore an existing company.”

2. Be certain to choose Open a company file, then click Next.

3. Click “Open” after finding the company file.

The software and data file are on the same local network (LAN) when using a Remote Desktop Solution (RDS) for QuickBooks, and processing takes place locally. QuickBooks is installed on a remote desktop that is viewed by remote users. This is a quicker, more dependable QuickBooks solution that is less likely to experience errors and time-outs. The data is stored on a server, the software is installed on the computer, and data processing, pushing, and pulling takes place over a VPN when using QuickBooks. It frequently times out and makes mistakes.

It is simple to let the initial cost be the deciding aspect. The issue is that once the cost is incurred and the VPN doesn’t work as expected and you experience endless QuickBooks errors, it’s likely that you won’t want to invest any more money in it and will instead choose to put up with the ongoing frustration and business issues it causes.

Why a VPN makes it difficult to access QuickBooks

Everything comes down to how the data is processed and stored, and how that affects how things work (or causes errors).

You’ll spend a lot of money.

You will be forced to use it even though it won’t work as expected unless you want to spend more money.

Spending the right amount of money on the right solution the first time is preferable.

Okay, moving on to the more technical information below. For small business owners, all the information needed is provided in the diagrams above.

Changing from Multiple Users to Single Users in QuickBooks

When closing month-end, QuickBooks may switch from multiuser to single user on purpose or more frequently on its own.

The multi-user daemon port may have been closed by Microsoft patching, causing the server to restart. Then, you have to use the QuickBooks repair tool to reopen it.

Note:  Additionally, it may occur if packets are dropped. Data bits that are pushed and pulled across your network are known as packets. On a VPN connection, packets are frequently dropped. Since QuickBooks is a live “flat-file” database, it struggles to deal with dropped packets. Typically, QuickBooks data files are large. They could be as big as 40MG. It may time out, produce errors, and terminate the operation when trying to access a file this size via a VPN on the open internet. Any additional connections to the QuickBooks file will be terminated at this point. The file must be repaired and will be put in single user mode. Additionally, it might corrupt the QuickBooks database.

Due to memory and latency problems, QuickBooks is slow when using a VPN. 

The only thing the daemon does when QuickBooks is launched from a laptop is route file share traffic through its own “QB managed” port. It still needs a file share, and the client application still downloads/loads the QB data file into local memory from the file share. Consider the repeated reads and writes that result from several users attempting to load the same shared file over a VPN at the same time. the large margin of error

Think about the additional encryption a VPN tunnel adds to file share traffic. It lengthens the time it takes for a packet to travel from its starting point to its destination and back. It’s less than 1 ms on a LAN. It may be 100ms or more when using a VPN. Millions of packets can be contained in a 40MB QuickBooks file. Users will be dissatisfied. Both ends of the VPN tunnel processing overhead rise as a result, making the user experience even slower.

Therefore, when using Remote Desktop Services for QuickBooks, no tunnel is used to route or encrypt traffic from the user’s laptop QuickBooks app to the shared QuickBooks database. It is LAN-specific (maybe even to the same physical machine over Hyper-V vlan switches). It is quicker, more reliable, and safer.

Remote Desktop Access to QuickBooks Is More Secure Than a VPN 

You can more easily make sure that company data stays on laptops that are owned and managed by the company when you use Remote Desktop Services. If anyone with a laptop and a tunnel can download all the financial information to their laptop, copy it to a USB device, and then do whatever they want with it, how can you prevent any data exfiltration? While we don’t mean to imply that your employees are unreliable, we always operate our IT Services in accordance with the principles of Zero Trust Security. The ideal scenario is this.

At least with RDS, there would be a log of that operation if someone were to copy the QB database to their RDS session desktop and then upload it somewhere else or email it to someone.  Better yet, you can implement cyber security guidelines to prevent RDS server users from accessing sharing websites or services (that you may not want to block on their local laptops).

This should clarify why a Remote Desktop Server for QuickBooks is the best option to:

  • Run QuickBooks remotely and more accurately.
  • More securely utilize QuickBooks
  • enabling you to apply IT security best practices to your data, computers, and users

  1. Why can’t I use a VPN to access QuickBooks Desktop?

    Due to bandwidth and file size restrictions, the majority of applications with databases or corporate data files do not function well with VPN. I would advise getting in touch with your IT department so they can help you set up the best connection for accessing your QuickBooks Desktop.

  2. How do I solve the QuickBooks updating problem?

    Due to restrictive firewall settings, QuickBooks may occasionally be unable to install updates, leaving you with the QuickBooks Not Updating issue. In this case, you must check the firewall settings by performing the actions listed below: Go to the Windows icon and type “QuickBooks Database Server Manager” into the search bar.

  3. Does QuickBooks Enterprise support VPN?

    Since 2007, QB Enterprise has performed extremely slowly and unreliably over VPN. Additionally, unless you *know* that the users will never open the QB files simultaneously, it is impossible to use Dropbox (Google Drive, OneDrive, etc.) for this purpose. Only LAN and RDP will allow QB to function correctly.

  4. I want to use Wan to connect to QuickBooks

    There is no WAN type that QuickBooks can operate over. On the QuickBooks local network, create a virtual machine and connect to it using RDP over VPN. Was this article of use?
