Is there a way to get this communication working? Maybe through my FRITZ!Box settings? I am not sure what is happening here: With the EPSV and PAS commands, the FRITZ!Box seems to send a new port (60770 / 59040), but then connects to an old one? * TLSv1.3 (OUT), TLS alert, close notify (256):Ĭurl: (7) Failed to connect to Port 32753: Connection refused * Failed to connect to u**************u. port 32753: Connection refused * TLSv1.3 (IN), TLS handshake, Newsession Ticket (4): Here is the terminal: $ curl -v -ftp-pasv -ssl -k -u speedITBackup 'ftp://u**********u.:32753/Backup/Superfein/'Įnter host password for user 'speedITBackup': The access to the NAS works fine when I access it from my (not locally connected) Laptop via WinSCP.īut when I try to access the NAS through the remote server of my webspace, the connection fails after the EPSV or PAS command. To ensure a static static servername (u**********u.), I activated and configured myFritz. I have configured a certain port (32753) for FTP communication. I am using my FRITZ!Box 3490 with a connected USB HDD as a NAS server.
