    Windows Defender Firewall is blocking Microsoft Phone Link


    When setting up Phone Link initially I had issues connecting the application. The application would say it requires a network connection. I reset the app to make sure something wasn't misconfigured, I made sure it wasn't DNS by pointing my DNS to 1.1.1.1 and 8.8.8.8. Next I made sure it wasn't something weird with my network and even removed my ethernet connection and connected my PC to the same wifi as my phone. Finally I completely disabled the Windows Defender Firewall. It only connected after disabling the firewall. After re-enabling the firewall the PC can no longer connect to the phone.

    :)

    Windows Firewall blocking websites

    I have blocked IP addresses, e.g. 255.255.255.255, not URLs, e.g. somewebsite.co m.

    As far as unblocking, look at your Windows Firewall rules. Do you see anything that is blocked? If you do, click on the Scope tab and see what is listed there.

    Block ALL Programs Except Allowed Ones

    You can block programs using Windows Defender, for example (ignore the strange title):

    Windows Defender Firewall is blocking Microsoft Phone Link

    Windows Defender Firewall is blocking Microsoft services

    Hello,

    I noticed that after the latest optional software update for Windows 10, the Windows Defender firewall is blocking Microsoft services: KB4550945

    In my case, it is not allowing downloading or logging in on the App Store.

    It even blocks logging in to outlook.com via browser.

    Turning off Firewall allows me to log in normally and perform app updates via App Store.

    Can this be checked please?

    Is there any additional information needed?

    Thanks.
