Windows 10: TLS security settings error - cannot connect to the Internet

Hi - hope someone out there can help me with this:


I have a laptop running Windows 10 Pro (Version 1803, OS build 17134.706). I'm having trouble connecting to the Internet via my web browsers. Regardless of which one I use, they fail when connecting to *almost* all websites. I'm getting the same or similar messages:


Microsoft Edge 42.17134.10

Cannot securely connect to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website's owner.

Your TLS security settings aren't set to the defaults, which could also be causing this error.


Google Chrome version 73.0.3683.103 (Official Build) (64-bit)

This site can't be reached.

www.google.com unexpectedly closed the connection.

Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics


Firefox version 66.0.3 (64-bit)

Secure Connection Fails

The connection to www.google.com was interrupted while the page was loading.

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this.


I've done some poking around online, and think the issue has something to do with the TLS security settings. I've read through this existing thread - https://answers.microsoft.com/ - but it doesn't solve my problems. I have ticked and unticked SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2 in all possible combinations but it hasn't made any difference.


If I reboot the computer, the problem seems to resolve itself for about ten minutes. Then it comes back again.


If I disable my anti-virus and Windows Defender then the problem also resolves itself but again only for about ten minutes. In addition to Windows Defender I have these antivirus programs installed on the computer:


Avast Free Antivirus
Version 19.3.2369 (build 19.3.4241.450)

Bitdefender Antivrius Free
Product version 1.0.15.101


I can't seem to isolate whether its Avast, Bitdefender or Windows Defender (or indeed any of them) that is causing the issue. Disabling any two of them is not enough to resolve the problem. I always have to disable all three. I can then reactivate some or all of them and the computer can connect normally to websites for about 10 minutes.


There's nothing wrong with the internet connection. There are numerous other devices in the house that are connecting online flawlessly.


There's also nothing wrong with the specific websites I'm trying to access. I can get them on my phone, my tablet, my xbox or my other computer.


This has also only started happening in the last three days. Before that Edge, Chrome and Firefox were all connecting perfectly to all websites. It's as if someone flipped a switch and now it's no longer working. Although I haven't installed anything or updated any settings myself in the meantime.


In addition to this laptop I also have a desktop computer which is running Windows 10 Pro, has exactly the same web browsers and exactly the same antivirus programs installed... but it is working fine. So I'm completely baffled.


Can anyone shed any light on what is going on here? I would be extremely grateful!


Many thanks,


Neil.

Microsoft Edge TLS Security


After trying everything (not a lot of steps) listed in the Microsoft Edge support site, I did a wider search and found this very simple youtube video that fixed it immediately:

For those who prefer not to click links the steps are simple:

1. Click in the Cortana search bar next to the Win 10 Start button

2. Type internet options

3. Select internet options (control panel) from the list

4. Click on the advanced tab

5. Scroll down to the security section

6. Make sure the following are all clicked:
Use SSL 3.0
Use TLS 1.0
Use TLS 1.1
Use TLS 1.2

7. Click apply

8. Refresh the page that was giving the error and it should now connect.

Hope this helps, it was a 30 second fix after hours of pounding my head against the error with the Support site suggestions.

We appreciate your response and the confirmation. To troubleshoot, we suggest the following steps:

• In the Windows Search bar, type Internet Options.
• Open the app and got to the Advanced tab.
• In the Security section, scroll down and add a checkmark to the following:
  Use SSL 3.0
  
  Use TLS 1.0
  
  Use TLS 1.1
  
  Use TLS 1.2
  
• After adding a checkmark, click on Apply then OK
  to save changes.

Give us an update about how it went so we can provide additional help.
