I am trying to establish a SFTP connection between aws SFTP and your SFTP with no luck.
Key generator I am using is Putty key generator, but I did convert putty private key to OpenSSH key and still got the error mentioned below.
Worth to mention that with the same key and passphrase I managed to connect from the company network to aws SFTP.
Error code that I am getting is:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
