I've created a new AWS server (Windows 2012 R2) and I'm not able to login into the server using telnet, as shown below. I've included screen shots as shown below to assist. I'm not sure what else I've missed? I've tried it locally and that works using the ftpuser I've defined.
Any help greatly appreciated.
FTP firewall settings
I get the following error when trying to connect from other machine
AWS security group settings
Update #1 - added TCP port 23 rule in AWS
Update #2 - checked FTP server is installed
Update #3 - Have installed telnet server
