Windows 10: TLS support on Windows 10

Hello everyoneI'm using a very old text-based email client called Alpine. It has worked very well on Windows7 but I am unable to install it on a Windows 10 PC - 64bit. When I do, I get this message about TLS:There was an SSL/TLS failure for the server imap.domain.comThe reason for the failure was Self-signed certificate or untrusted authorityThis is just an informational message. With the current setup, SSL/TLS will not work. If this error re-occurs every time you run Alpine, your current setup is not compatible with the configuration of your mail server. You may want to add the option /notls

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.

 

Intermittent problems with TLS handshake and being timed out

Check DNS settings for both network adapters. Your Wifi might be set to use a different DNS server.

Option Two follow steps then pick a DNS server from the list in item 7. Personally I use CloudFlare DNS

EDIT: Reset router first as already suggested.
