Windows firewall is blocking quickbooks.

Every time I run QBDSM, this keeps popping up. I have searched and did everything recommended that I found, including checking the ports. Even uninstalling and reinstalling on both computers. I have run the file doctor multiple times. Even the desk top install diagnostic tool. Even if I turn off windows firewall, I still get this. And under the Database Server tab, it says no files are connected. My file is stored on an external hard drive. I need this to work. I did not have a problem before. My hard drive crashed and had to reinstall QB. Now, I can sync the company because of this.

Ok, I kind of fixed the problem. I reset windows firewall back to factory settings. That seems to of worked. I no longer see it blocking in the QBDB Server Manager. But, now it is my Avast - "avast antivirus antivirus is active on this computer and may be blocking quickbooks". I am using the free version. I have never had this happen before and have used both QB & Avast together for years. When I turn Avast off and run QBDB Server Manager, all is normal. Turn it back on and I get "avast antivirus antivirus is active on this computer and may be blocking quickbooks" when I scan folders. At least now under the Database server tab, I can see both computers either way now. But, when data is entered in one computer, it does not show on the other. I did go into exclusions in Avast and set up QB, but that did not seem to help.

Hello @buddykonz,

This is something to do with the security of your computer. Windows firewall and antivirus usually blocks some software from running in the system. You'll need to add the programs under the firewall and the antivirus to allow them from running. You can also consult an IT guy to configure the settings.

Please keep us posted.

I'm also having this issue and i'm sure it's related to users not being able to switch to multi-user mode. They receive the H202 error when they try. I'll scan the company files on database manager and receive that error "windows firewall is blocking quickbooks". I've manually configured the firewall based off the article listed above but i still receive the message. File doctor says everything is okay on both my server and client computers. Also, the only way a user can switch to multi-user mode is if the company file is already open as multi-user mode on the server. I've called quickbooks a few times but we have not been able to get this going. The only thing i havent done is reset windows firewall back to factory settings but that's something i really dont want to resort to.

I'm having the same issue as buddykonz.  Opened the firewall up wide to both the ports and programs, but still get the error message.  I've tried calling Intuit tech support but balk at the idea that *I* have to pay to fix *your* buggy product.

You need to reset the firewall back to factory settings. That is what worked for me.

I am having the same problem. New server and computers. Fresh QB install. Users cannot open in multiuser mode unless you open the server first in multi user mode. I have added all the firewall rules and when you click Start Scan it says Windows firewall is blocking Quickbooks. When you run the Quickbooks file doctor it says everything is fine.

Re: You need to reset the firewall back to factory settings....

Is there a script or anything (such as QB File doctor) that will automate the process of firewall passthrough if we reset the firewall components?  Having ALL the same issues here.. but manually entering every rule/port, etc is a bit time consuming if we have to do it from scratch.  Will the new version of file doctor or anything else (script)? Do that automatically for us?  I noticed that somehow the QB Database Server manager was not launching automatically on boot, but once open (even though it errored out communication was restored between the two computers.  We fixed the start-up issue and rebooted 4 times and everything was working awesome (almost like we were hosting QB on the client pc it was so quick), however apparently the next morning it reverted to the same problem again (not sure of the cause).

Re: You need to reset the firewall back to factory settings....

Thanks for dropping by the QuickBooks Community, CAT Computers.


I appreciate you providing me the details about the steps you’ve taken to resolve the issue. I want to ensure the QuickBooks Database Server Manager will properly work on your computer.

 

Currently, QuickBooks doesn’t have the option to automate the process of configuring firewall components. We have to manually add the rules and ports depending on which anti-virus you're using.

 

To help you get back up and running, we’ll need to check the setup of QDSM. The safety and security of your account is our top priority.

 

Since the Community is a public space and were unable to gather sensitive data to verify your account, I recommend contacting one Technical Support Team. They have the necessary tools to trace where the issue is stemming from, and provide a solution to fix it.


The most up-to-date contact information for Technical Support can be found here:

 

  1. In your browser, navigate to: https://help.quickbooks.intuit.com/contact.
  2. Choose your QuickBooks Product.
  3. In the Contact Us page, click the issue or topic.
  4. Click on the Green Phone button to see the support number.

Upon giving them a call, you'll be able to run the QuickBooks Database Server Manager without any issues.


If there's anything else that I can help you with, post a comment below. I'd be glad to assist you further. Wishing you the best.

Re: You need to reset the firewall back to factory settings....

I'm having a similar problem.

 

I am upgrading to QuickBooks 2018 Premiere, and trying to use QuickBooks with a dedicated Windows 10 Pro machine as server. That is a new and clean installation, and only the QuickBooks Database Server Manager is installed on the machine.

 

File sharing is working, and I can connect to the company file from a workstation.

 

However, both QuickBooks Database Server Manager and File Doctor give the following error message:

 

“Windows Firewall: Connection Sharing not allowed”

 

No third-party firewall or antivirus software is installed. 

 

I have worked through the HOWTOs on installing QuickBooks for this type of installation, and on manually configuring the firewall. The necessary exceptions for both ports and applications seem to be present. Firewall logging shows no blocked ports.

 

I'm wondering if there could be an incompatibility between the current version of Windows 10 Pro and theQuickBooks Database Server Manager in QuickBooks 2018 Premiere.

 

Does anyone recognize the error message: “Windows Firewall: Connection Sharing not allowed”?

 

Any help would be very welcome!

 

Thank you.

Re: You need to reset the firewall back to factory settings....

Hello Tim Rogers,

 

Thank you for providing more details about your concern.

 

The error message tells us that your firewall blocks Internet access needed for specific QuickBooks programs or files. Let's update or configure your firewall to the latest release to resolve this issue. 

 

Please refer to this article for the complete steps: Configure Firewall and Internet Security Settings for QuickBooks Desktop

 

Once done, please restart your computer and access your QuickBooks again.

 

Let us know if you have any questions.

Re: You need to reset the firewall back to factory settings....

Thanks for the reply. 

 

I'm afraid that I've already worked through that HOWTO.

 

I have manually added the port and program exceptions to the firewall. Same error. Disabled the firewall completely. No change. Restarted the computer, uninstalled and reinstalled the QuickBooks Database Manager. No change.

 

I also enabled logging for the firewall. It showed no blocked ports.

 

Do you have any other suggestions?

QuickBooks Team

Re: You need to reset the firewall back to factory settings....

Let me join this thread and provide a different suggestion, Tim. 

 

I would recommend contacting our Technical Support Department. They have additional tools that can check why you're still getting the error even after following the recommended steps. 

 

Here's how to reach out to them:

  1. Open this link: https://help.quickbooks.intuit.com/en_US/contact.
  2. Select QuickBooks Desktop, then select the version that you're using.
  3. Click Solving Issues and Error Messages.
  4. Click Common Errors, then click Get Phone Number.

You're can visit us again in the future if you need help while working with QuickBooks.

Re: You need to reset the firewall back to factory settings....

Thanks.

 

I've already spent an hour or so with support, and have a case number. When I have a couple of hours to devote to this, I'll try again - if I can't get this sorted out another way.

 

I was hoping that someone in the community might recognize this particular error message and have a suggestion, however. 

 

Alternatively, if I could get access to the "additional tools" and information that they might use, that would be helpful. 

 

Again, my basic question is: If the error message references the Windows Firewall as the source of the issue, why does turning it off not resolve (or at least change) the error message? And why does the Firewall logging show no blocked ports or applications? Could it be that it isn't really a Windows Firewall issue after all?

 

Thank you.

Re: Windows firewall is blocking quickbooks.

Please follow the below solutions, and that should help you in fixing the issue quickly.

 

Method 1: Firstly, Launch Windows Firewall and check to look if the essential ports for QuickBooks are available or not. These sections for QuickBooks 2015 are 56725, 55367, and 8019. In spite of these being available, you may still require to check out more over updating. In this way, a user can proceed in Windows Firewall to Find blocked ports. This should fix your errors of Windows firewall blocking QuickBooks or QuickBooks Hosting.

 

Method 2: You can install, download, and run QuickBooks file doctor. It will naturally open the blocked firewall ports. You can also set up Windows Firewall with this tool. This should hopefully fix the matter.

 

Regards,

Adrian
