Windows 10: TLS Error on Websites that have passed SSL Lab and TLS settings are correct- WINDOWS 10

On Internet Explorer 11, I have set my GPO to only use 1.1 and 1.2. There are a couple sites I go to that I get TLS errors on. I go to SSL Labs site and the sites get an A saying that only 1.1 and 1.2 are being used. I've talked to the sites and they are using 1.1 and 1.2. By all accounts the sites should work.

Here's the kicker, some times the site works and some times it doesn't. AND with the same settings, I have zero trouble with people using these settings on Windows 7 computers.

I don't know what I can do to make sure I'm not getting these errors. Any suggestions would be great.

:)

 

TLS AND SSL

WOULD YOU KINDLY ADVISE ME IF THE FOLLOWING SHOULD BE ENABLED ON MY COMPUTER SSL 2.0, SSL 3.0 TLS 1.0 TLS 1.1 TLS 1.2.

 

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.

 

TLS AND SSL

TLS 1.0 TLS 1.1 TLS 1.2 should be enabled not SSL 2.0 or 3.0 as there are security vuls for SSL 2.0 / 3.0 which can be exploited.

There is also a security advisory from Microsoft for SSL 3.0 - Vulnerability in SSL 3.0 Could Allow Information Disclosure -
