An FTP error occurred - cannot put [file name.htm]. Dreamweaver encountered an internal data error

i message “server not responding” whenever trying add files web site via dw. following message appears: "an ftp error occurred - cannot put [file name.htm]. dreamweaver encountered internal data error. please try operation again." 

 

i called hosting service provider, , said able upload 20 mb document no problem. able upload document using filezilla.

 

therefore, problem must dw.

 

when go manage sites , choose site , test connection button, test successful, further confuses issue.

 

any guidance appreciated.
