Errors thrown by With Ftp Session activity

I have configured the With Ftp Session activity with the following:

However after I run it I get the following error message:

RemoteException wrapping System.InvalidOperationException: The argument of type 'System.Boolean' cannot be used.  Make sure that it is declared on an activity. 
   at System.Activities.Argument.ThrowIfNotInTree()
   at System.Activities.Argument.Get[T](ActivityContext context)
   at UiPath.Shared.Activities.ContinuableAsyncNativeActivity.BookmarkResumptionCallback(NativeActivityContext context, Bookmark bookmark, Object value)
   at System.Activities.Runtime.BookmarkCallbackWrapper.Invoke(NativeActivityContext context, Bookmark bookmark, Object value)
   at System.Activities.Runtime.BookmarkWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

I have checked the credentials and the port and the ip that is supplied. They are correct. However I continue to hit the same error. Please assist.

Hey @RobinsonFrancis

Were you able to connect to this server when tried manually please ?

May be you can try using WinSCP or Putty or any other tool

Thanks

issue was more often reported by users. Maybe you can do a cross check with an alternate like ping, telnet… if FTP server can be reached with provided details. Optional also check for firewall blocks with the IT Team
