@Ivaylo I was able to make it work but not using port 21, I used port 65000. In my opinion, there is a bug here. Also, you were right about the passive settings. Thank you very much.

@Ivaylo I have opened the ports but they are still closed. Maybe this is due to the FTP function using USB. But I am not using the USB. I want the FTP connection to be on the local IP 192.168.10.11....

Cannot make it work. Even with the FTP preset in the router.

I cannot setup FTP port forwarding to my PC. The port scanner shows that the port is still closed.
