FTP error - 421

[Former Member]

Hi all,

We are trying to FTP files from business connector at regular interval to external party via proxy and sometimes we face a error - 421 Service not available, closing control connection.

Please help to know what could be the cause for this, as this happens during few transmissions and remaining time we are able to FTP with out any problem.

I tried to check the size of the files transmitted and is not different than the successful transmission. Also, due to this error we are not able read or put the files to external FTP server.

Please help.

Check the overall availability of the external FTP server and the network connection to it. Has surely nothing to do with Business Connector.

Sounds just as if the FTP server is not always available.
