Fatal Error: Remote Side unexpectedly closed network connection

#1 Post by jminshull » 2020-12-15 17:01

HI,

I am wfh since March and during this time I have been unable to get filezilla to connect. My coworker are all able to connect.

I get the following error message:
Status: Connecting to 66.179.143.142...
Response: fzSftp started, protocol_version=9
Command: open "apus_prod1@66.179.143.142" 22
Error: FATAL ERROR: Remote side unexpectedly closed network connection
Error: Could not connect to server
Status: Waiting to retry...

I've run the network configuaration wizard and that connects successfully set up as: passive, use servers external IP address, and get external from URL. If I use my operating system external IP I get a message that say my external IP doesn't match.

The test uses FTP, which connects through the main executable. SFTP uses a separate executable (fzsftp) and has to be separately allowed in the firewall.
