Untrusted Server's Certificate

Hi, more details are welcome.

The solution in this video is working for me: https://www.youtube.com/watch?v=JDQzlWSyvjY . In short, search preferences for certificates or go to Tools -> Server Certificates and check "Accept non-trusted certificates automatically."

However it's unclear to me what the security implications are of unchecking that box. While my experience is that most certificate warnings on the Internet are displayed out of an abundance of caution, I have to figure it was unchecked for a reason. Can anyone illuminate the circumstances where it would be safe versus unsafe to check that box?

It's simple, untrusted certificate means there is no guarantee that your connection to the remote server is secure, and prone to man-in-the-middle attacks.

If you transfer really sensitive data over the net (your coprorate code-base to an external git repo, for example), you should always ensure the certificate is issued by a trusted CA.
