Jenkins 2.46.1 does not support to have a ssh connection with default pem file from aws. To do the automatically deployment from Jenkins server, a ssh connection should be establish from Jenkins server to the instance.These are steps to do to enable the SSH connection:AWS instance:
  • Create a new user on the instance
  • Edit the SSH config file to enable Password authentication for SSH and especially, specify some special encryption algorithms that supports Jenkins 
File: /etc/ssh/sshd_config


Put this at the end of the file

HTTP_REFERER

A friend of mine ask me if a server can know where we come from before we go to that server (referal link). YES. This information is the field "HTTP_REFERRER" in $_SERVER of the coming request.
