Check the "encryption" item in the connection options.

Traditional FTP connections exchange authentication information in plaintext, so it is currently deprecated.
"FTP over TLS" is often used instead, which must be adapted to the configuration of the destination server.

"FTP over TLS" is selected by default when attempting a new connection with FileZilla, so try selecting ""Use only plain text FTP"" depending on where you connect."
