I'm still getting the error after trying the solutions here. Any other ideas how to solve this? I'm using a CentOS 7 server (64bit, x86), on AWS.

Below are the messages from FileZilla.

Status: Connecting to XXX.XXX.XX.XXX:21...
Status: Connection established, waiting for welcome message...
Status: Logged in
Status: Retrieving directory listing...
Command:    PWD
Response:   257 "/" is the current directory
Command:    TYPE I
Response:   200 Type set to I
Command:    PASV
Response:   227 Entering Passive Mode (54,145,XX,XXX,206,110).
Command:    MLSD
Error:  The data connection could not be established: ETIMEDOUT - Connection attempt timed out

54.145.89.103 is not the address I'm trying to connect. My server IP is different. I think it's ProFTPD server.

Based on your comments, your FTP server is not correctly configured to announce its external IP address in PASV command response.

With ProFTPD server, you need to update the MasqueradeAddress directive in proftpd.conf.

See also ProFTPD: Firewalls, Routers, and NAT and my article about network setup for FTP.
