@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: UNPROTECTED PRIVATE KEY FILE! @

Permissions 0555 for 'YYF_Frankfurt.pem' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "YYF_Frankfurt.pem": bad permissions
ec2-user@ec2-XX-XX-XXX-XX.eu-central-1.compute.amazonaws.com: Permission denied (publickey).
I followed the instruction and use chmod 400 to change permission. However, the permission did not change.

Ah now I notice. Yourpemkey resides on a Windows drive which obviously doesn't use Linux-type permissions. Move your key to a Linux drive.
