Cannot list files with FTP server from the 90s

Hello,

Could you please explain me what I'm supposed to do to workaround this issue ?
If I understood other tickets correctly, the issue comes from MLSD not being supported but I read somewhere you're doing fallback to LIST, but it does not seem to happen here...

Thanks in advance !
