closeed EPSV

curlsetopt($curl, CURLOPTFTPUSEEPSV, false);

or of CLI:

--disable-epsv

If it repeats (classic problem behind NAT)

add this

curlsetopt($curl, CURLOPTFTPSKIPPASVIP, true);

Bu çok kritik çünkü bazı server’lar PASV içinde private IP gönderir:

227 Entering Passive Mode (10,0,0,5,195,44)

curl tryed for connection → unreachable → fail.

this option:

“Sunucunun söylediği IP’yi değil control connection IP’sini kullan”
der.

Root that is

Firewall FTP ALG is open:

nfconntrackftp

and EPSV can pocket wrong rewrite.

for Linux’ta

sudo modprobe -r nfconntrackftp
sudo modprobe -r nfnatftp

curlsetopt($curl, CURLOPTFTPUSEEPSV, false);
curlsetopt($curl, CURLOPTFTPSKIPPASVIP, true);
