Windows 10: Windows prevents internet connection through Apps/Launchers even with defender and firewall...

This has been an ongoing issue and I am unsure of what I need to do here. When accessing apps like HP on my Windows device it will prevent the app from loading a page, I need to refresh it a few times for the page to go through. The same happens when using game launchers from Steam or WarGaming. My Chrome and Edge work perfectly. I have another computer that accesses the internet through games and apps perfectly so it is not on my router. The problem persists whether it is WIFI or Ethernet. 300 mbps I have even done a fresh Windows install on a new SSD.I have made sure my ethernet and wi

W10 can connect to wider internet but cannot access web pages

I have an odd issue with my W10 laptop linked to Sky broadband in the UK via wifi using a Sky router. The effect is that while I can actually access the internet (I can send and receive emails using Outlook and can connect to other machines using TeamViewer) I cannot access any web site (Google, BBC etc). There is no specific error message, merely that the access request timed out and a suggestion that it may be to do with proxy.

I have tried the following:

1. Other systems (W10 and ios) can access web sites using the same Sky router (therefore probably not a router problem)
2. I have sent and received emails using Outlook, so the broadband connection is working (probably not a Sky problem)
3. I have tried two different browsers (Firefox and Edge), no connection (not a browser problem)
4. I am using Windows Defender and have:
   1. Made sure that Firefox is in the list of allowed systems in its Firewall, no connection after a reboot
   2. Turned off the Firewall and tried again - no connection

My next step will be to re-install Windows, but has anyone got any other suggestions? Could it be some sort of virus (I have carried out a complete virus check using Defender)

So - any suggestions?

 

Internet connectivity

Thank you for sharing more details. We would like to verify you are using the Windows Defender Firewall so we can isolate the issue. In some instances, the firewall is blocking the internet connection when using certain apps. At the same time, we also suggest
the following methods below for initial troubleshooting.

Step 1: Run the Windows App Troubleshooter. The troubleshooter can help identify
and repair problems automatically.

Step 2: Modify the connection settings in the Internet Options.

• In the Windows search bar, type Internet Options.
• In the Internet Options window, go to the Connections
  tab.
• Under the Proxy server section, untick the Use a proxy server for your LAN.
• Click OK then Apply and OK
  again to save changes.
• Launch the apps and check if you are able to connect to the internet.

After following these basic steps, let us know the outcome so we can give you additional help.

Kind regards.

 

Defender Firewall will not save "allowed app" rules

I am having a persistent, ongoing problem with allowing apps through Windows Defender Firewall (Windows 10 Pro 1809). Basically, the firewall is not remembering when I add an app to the list.

From the control panel I am going to "Allow apps to communicate through Windows Defender Firewall". One of the apps in question is already listed and I need to continually enable it through the Public connection. But the rule doesn't stick.

Another app is missing from the list so I manually add it, and things work fine for that session. If I restart the system and go back to these rules, the manually added app is no longer in the list, and the already present app in the list has again reverted to Private only. I have to constantly reset these.

Why won't these apps stick in the allowed apps, and how do I fix it?
