Business Service Error on Windows 11 machine

#Business Service #FTP #SSL #InterSystems IRIS for Health

Good day 

I am trying to connect a business service to fileZilla using FTP on my local PC Win 11.

I am trying to setup my training after attending the Building HL7 interfaces course with ISC.

The connection is failing. He is the error below

 

ERROR <Ens>ErrOutConnectFailed: FTP Connect failed for localhost:21//SSL=' with error ERROR <Ens>ErrFTPConnectFailed: FTP: Failed to connect to server 'localhost:21//SSL='/' (msg='Missing required argument',code=501)

The error message indicates that the connection to the FTP server is failing due to a missing required argument, identified with the error code 501. Here are troubleshooting steps and relevant settings that could help address your issue:

  1. Verify FTP Settings: Ensure that the FTP server settings such as server address (FTPServer), port (FTPPort), username, and password are correctly configured. These settings need to be defined within the FTP adapter or session you are interacting with. Use the FTPServerSet() and FTPPortSet() methods for configuring the server and port, respectively [1][2].

  2. Configure SSL/TLS Settings: If you're using SSL/TLS, ensure the configuration is correct. The SSLConfigSet() method allows specifying the TLS configuration entry for authentication. Incorrect or missing SSL configuration could cause issues like the one in your error message [1][2].

  3. Check Credentials: Use the CredentialsSet() method to specify the production credentials entry authorizing the connection to the FTP server. Ensure the credentials match those of the FTP server [1][2].

  4. Invoke Adapter Test: Use the TestConnection() method provided by the FTP Adapter to verify the connection state. This method can help correct connection-related properties if the adapter thinks it is connected but has lost the socket [1].

  5. Error Code 501 Analysis: The error code 501 suggests a protocol error, possibly due to missing arguments during connection initialization. Examine any mandatory parameters in your FTP setup that might be omitted [1][2].

  6. Debugging and Logging: Follow InterSystems guidelines for debugging FTP connections, possibly using logs or additional parameter tracing frameworks [2].

Example code snippet to configure the FTP settings:

Set sc = ##class(%Net.FtpSession).FTPServerSet("localhost")
Set sc = ##class(%Net.FtpSession).FTPPortSet("21")
Set sc = ##class(%Net.FtpSession).CredentialsSet("username_password")
Set sc = ##class(%Net.FtpSession).SSLConfigSet("SSLConfigName")
If $$$ISERR(sc) { Write "Error configuring FTP settings! ", sc }

Ensure FileZilla and the FTP adapter are configured for correct environment compatibility and log events to identify any specific errors [1][2].
