FTP file transfert error

Hello,

I’ve been experiencing a file transfer error via FTP on my scenario for several days now, even though it worked fine before:
I create an image with gpt-image-1 , the new gpt chat image tool, I convert the base64 to binary and send the data via ftp to my hostinger server but I still get this error:

RuntimeError
None of the available transfer modes work.

Origin
Make

Automatic error handler
If you want to handle this error automatically, choose one of the following options. This will create a new error-handler route in your scenario. You can then expand the route in any way you like.

I’ve been testing for days and I can’t find a solution.
i’ve inserted a “converter” image module and given it the data and .png file name. the transfer works, but the image isn’t displayed on my site, but the file is correct when i open it from the file explorer on hostinger …

testing connection : OK
