FTP connection closed without indication

I am trying to move file from local folder to remote server. I initially used File connector, if I give the server path in properties file and access it through File connector, I am able to move the file to Server location. But I need to get the server path dynamically from a call to another api. I stored the path in flowvariable and used it in File connector. Then its not moving file to server.

I tried using FTP connector but facing this issue: Message : Connection closed without indication. (org.apache.commons.net.ftp.FTPConnectionClosedException)

I used this: ftp:outbound-endpoint host="cd01-fs1.com" port="80" path="dit_hr_eh\\clientdata\\nem2hp\\batch\\temp\\21d" connector-ref="FTP" outputPattern="fvFileName" responseTimeout="10000" doc:name="FTP"

Could anyone help with this. Thanks
