amazon ec2 intance rhel7 ftp not downloading

Question

this is driving me insane.

i am trying to download files using FTP. i tried with PHP's FTP, the FTP binary, WGET, none of them work. They all have the same problem. When get command is initiated, the client hangs and never completes or throws any errors. This only happens on Amazon EC2 instance (RHEL 7). This has previously worked on CentOS instance and also works locally on my Windows machine but for some reason does not work on Amazon's RHEL7 instance.

I have:

• Opened ALL incoming/outgoing ports in Amazon security group
• Disabled iptables and ip6tables.
• Disabled SElinux.
• Set 777 permission on the local target folder.
• Running PHP/FTP/WGET using sudo.
• Used passive or active mode ad nauseum.

The remote FTP file exists I know that for a fact. There is something, and I don't know what, that prevents THIS specific Amazon instance from initiating an FTP download. Has anyone ever encountered this before? It's driving me INSANE.

Answer 1

My best guess is the host isn't routable meaning it either doesn't have a public IP or there is some VPC configuration affecting the communication since you state wget doesn't work either.
