This Wiki is based on Forum Thread: FTP adapter Connectivity Error

Problem

Sometimes while configuring/using FTP Adapter on send port, we face connectivity issue with following error:

"The remote server refused a data connection.

Please check permissions on the remote system."

Solution

To solve this issue, we need to check two things:

  1. FTP Authentication settings in IIS
  2. FTP Authentication settings on FTP Send Port

FTP Authentication settings in IIS

To check the FTP Authentication settings in IIS, perform the following steps:

  1. Open IIS Manager (Ctrl + R --> inetmgr)
  2. Expand Sites and go to Default FTP Site
  3. In FTP Settings, double-click FTP Authentication

  4. Verify the FTP Authentication --> Basic Authentication is Enabled (Enable if it is Disabled)

FTP Authentication settings on FTP Send Port

Now check authentication settings on FTP Send Port:

  1. Go to FTP Send Port --> Configure --> FTP Transport Properties
  2. Check the User Name and Password. The user should have rights on the specified FTP Server.

The issue should be resolved by performing above steps.
