425 No data connection

[Boby270]

Hi, I'm trying to use the SimpleFtpServer library to implement it on an Arduino GIGA R1 Wifi. This board has a murata 1DX wifi chip, the same one used on some ESP32 (wifi.h), and also has an STM32 microcontroller. So I said to myself that by defining the NETWORK_EPS32 macros as well as the type of storage I use (with the SdFat.h library) and by indicating that I'm on STM32 via the macros I could make this library work on my board.

I've managed to set up my card's wifi network in AP mode, to which I can connect via a filezila client, but when the MLSD command is sent I get an error which is 425. it can't establish a connection to send data, if I've understood correctly. So I can't see the contents of my SD card or interact with it. Filezila is configured in passive mode and with 1 connection at a time.

can you help me and maybe show me a solution to solve my problem? thank you in advance. :')
