Flight simulator 2020 block by firewall


I install Flight Simulator 2020 by Microsoft Store.

But the firewall of BitDefender block the game. Only if a desactivate the firewall that the game connect.

How can i make an except rule with the firewall with an app on windows 10?




  • I did a ticket for the same problem, no solution for the moment , maybe if evry user of Fs2020 contact the support, they will give more time for this problem.

  • Below is a reply from Bitdefender CS received yesterday


    Thank you for your patience throughout this entire process and please accept my apologies for the frustration that we might have caused.

    I have looked into the case and it seems that the situation is caused by an issue which has already been acknowledged by our development team. We are currently working on a fix which will be done by means of automatic update and won't require any additional action on your end.

    I will get back to you with an update regarding the fix as soon as we have one.

  • I did open my ticket too and also received the same answer as @Fbsh . I thought the recent patch released by Microsoft would handle the issue but it looks like it didn't.

  • Same Problem.

    Same issue, even when adding a FW rule and putting EXE path manually. I had to disable FW to get it to update.

    Seems a lot of software lately is having issues with UWP apps?

    There probably needs to be a better way to adding Windows Apps to FW rules etc, similar to how nVidia handles them in their Geforce Experience .

    And I just paid for a one year subscription to Bitdefender; stuff like this needs to not re-occur.

  • Hello, everyone. I joined this community to gain new things and to be honest i don't have much knowledge in this field, i'm facing some type of tech issue, from yesterday my roku remote not working. Help Me. Thanks in advance

  • Hey, everyone. Hope you all are good. I joined this community to share as much as knowledge in this online field, so yesterday my roku freezing screen problem started, then i searched many ways on the web to fix it. If anyone also want to know then lets have a healthy discussion. 

  • No news coming from Bitdefender about this issue. Currently having to rely on Windows Defender Firewall, but not satisfactory long term solution. Frustrating and not good PR for Bitdefender.

  • Hi, you can do the following. Go to Protection>Firewall>Settings.

    For ´´Default application behavior´´ click ´´Edit default rules´´´.

    For WLAN take the setting ´´Allow´´. OK

    Same issue here. No problems but problem only began recently.

    On Automatic settings - Firewall does not let Microsoft Flight Sim 2020 go through firewall.

    No Firewall settings for ASK? Only - BLOCK, ALLOW or AUTOMATIC

    How about a setting to turn firewall off for an hour? Or even better - ALLOW for xx (15 minutes, 30 minutes, 120 minutes) time period??

    Tried adding rules based on location of executable but that did not work

    Seems kind of problematic to turn off firewall to play a known game - not to mention huge security risk


    PS: As one of previous posts mentioned - how about adding folders to exemption rule - such as WinApps

    Hello there.

    I have the same issue. 2 days ago when I started Microsoft Flightsimulator 2020 I did get an error. After I've tried some things I found out that BitDefender Firewall was the issue... pretty strange though, because this wasn't an issue before.

    When I started Flight Simulator it began to download the latest patch (v1.9.5.0) with no problems.

    When I enable the BitDefender Firewall now before I start the game, the Market Place option is grayed out and the game says there's no internet connection.

    The only solution for now is to completely disable the BitDefender Firewall... I also tried to create a rule for the 2 FlightSimulator.exe files but this doesn't solve the issue:



    I hope BitDefender will fix this soon so I don't have to disable the BitDefender Firewall anymore when I want to play Flight Simulator 2020.


  • Today I updated my Bitdefender to the latest version and now I have to turn off the Firewall to allow MSFS to work otherwise I get the insert disk issue. I've tried adding it to the firewall, etc.

    MSFS was working fine on the previous version of Bitdefender.

  • With MSFS 2020 being one of the most downloaded flight sims in recent memory, I fail to understand the delay on Bitdender's part to address / fix this?

    My BitD subscription is coming up and there are other solutions out there that have little to no issues with MSFS 2020

    Could we please get confirmation from Bitdefender folks that they are working on a fix???

    Thank You

  • Last email from tech support was basically "we're working on it". Issue is well over a month old....

    I suggest you send support a message expressing your thoughts.

    Between this and FW rules not working ... oof

    Not sure how these issues got past testing.

  • As people said her, It's been over a month now and no fix has yet to be released.

    It's not exactly rocket science, just create a rule to let MSFS work with BT and release it to the users. MSFS was already updated twice since this issue was published and no fix yet was published.

    Seriously thinking of going back to my previous provider.

  • I have the same issue after updating Bitdefender.. Took me a while to even work out what the problem was. Please fix this Bitdefender!!
