FTP Stops Working

[jakbaaw]

Hi,
I'm new at this so if I leave out something critical please let me know.

I'm having some trouble with ftp-download. I've tried some other node-red ftp nodes and have had similar trouble so I'm thinking this is my application, but I can't find where.

The situation is I'm trying to pull some simple .txt files from an FTP server hosted on an industrial device. I want to do this in short intervals. Then I process the data in those files. The issue I run into is that if I execute the FTP node more than a couple times it stops pulling the files and nothing comes out on the debug node on the other side.

This .jpg shows the flow after one execution.

This .jpg shows the flow after the second execution. Notice that two messages come through with one execution of the flow, which seemed peculiar to me.

After that I get nothing. I can still access the FTP server from other applications, just not through node-red.

That is really odd, is the server set up by you? Do you know if it has any throttling enabled, or any kind of ddos prevention measures? I can't imagine why it would be caused by node red, I've used this node to hit the same ftp file location thousands of times in a row successfully.

The FTP server is set up on an industrial device (it actually communicates primarily over Ethernet/IP). I doubt that it is throttled or has DDoS prevention beyond what is specified for Ethernet/IP. However, the network currently is a single PC and this industrial device so I don't think it should be a problem with overflow as the file transfers are the only traffic on the network. I am able to use labview currently to pull the files from the FTP server and Node Red is using the local files saved from the server. I have had no trouble running this way. I'm able to run the application as designed now, but will hope to come back to this issue at a later time and troubleshoot a little more. Is there any data I can collect for you that might be helpful?
