Error: Failed to retrieve directory listing

[jwr0014]

This is driving me crazy, I've googled so many times and the solution that comes up 90% of the time is to change to active transfer or to use plain FTP. I've done this a million times, still no dice. This is what my client is outputting except I've put asterisks over my servers IP:
Status: Connecting to **.***.***.***:*****...
Status: Connection established, waiting for welcome message...
Status: Initializing TLS...
Status: TLS connection established.
Status: Logged in
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is current directory.
Command: TYPE I
Response: 200 Type set to I
Command: PORT 10,255,97,60,197,170
Response: 200 PORT command successful.
Command: MLSD
Response: 150 Starting data transfer.
Response: 425 Unable to build data connection: ETIMEDOUT - Connection attempt timed out
Error: Failed to retrieve directory listing

Please help, I got rid of the timeout hoping that would help and I think it did because I got the output above but I always get the failed to retrieve directory listing error. It's not my firewall or my port forwarding, I can connect if I'm on the local network using the local IP address or the public IP, I just can't connect on any other networks.

Switch to Passive mode, it's recommended over Active for NAT/firewall scenarios. See the Passive mode part of Network Configuration.

If you must use Active, you need to configure the client and the client's network. See the Active mode part of Network Configuration.

After testing with just passive mode, this is what I get. Pretty much the same thing. Any other suggestions?

Your firewall somewhere is not properly opening up the data ports.

Protocol transmits on one port, data moves on another - This behaves like a firewall issue either at the client or server side...

Per your notes, it works on local network - most local NATs don't need ports opened - because they're ALL behind the firewall. Not being able to FTP outside of your router means you have a firewall/NAT issue at the router blocking communications between you and the outside world (on the data port only)...
