GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated.

[Spoon86]

Hello,

I set up an Filezilla Server on Win11 to let my Relinkcam's drop videofiles on it.
This works completly fine. Also if i try to connect with the filezilla client form the server to reach the server works fine. (using the ip adress)
Now i want to download the files from my desktop Pc. But i cant connect to the server.

There is a firewall in between the Desktop PC and Server that is blocking PASSIVE mode transfers -- additional ports are required to be opened to support PASSIVE mode.

The Network Configuration guide: https://wiki.filezilla-project.org/Netw ... figuration may provide clues or assistance to solve.
