I'm trying to setup SSH over HTTPS. I'm on Windows, using OpenSSH trough Git. I have already created the keys and set the configuration for the alternative ssh server from the guide. I tried testing the connection with the command:
ssh -Tvvv git@bitbucket.org
But there is a connection error. I need help debugging it, due the fact that every source of information related to the error referes to the fact that "you tried SSH over an HTTPS server" which is what I'm suppoing to do to bypass the 22 port and make use of 443 thanks to atlassian. Here the log:
$ ssh -Tvvv git@bitbucket.org
