Closed without indication

[Rocky]

Every so often we get FTP projects that fail. The only error is that the FTP session was closed without indication. What does this mean?

Roc,

This could be one of many reasons. Dropped line, server IPL, Router or Switch issue.
We have no way of determining that unless we get information from the Target Server.

Rick,
How would I go about finding out which of these many reasons was the one causing a specific failure?

Get a detailed log from the Customer/Trading Partner indicating the reason for the dropped connection would be the best place to start.

Rick,
So just to be clear about this - you are saying that GoAnywhere could not possibly be at fault in such a situation, yes?

Roc,

What I'm saying is .. there's no way, just from that message, to determine what the exact reason was for disconnecting.

What I will say (and my assumption is that you are trying to FTP a document to some Resource) is that, setting up your Resource to perform Retries with a Delay will usually keep these types of issues from happening.

On your CONNECTION Tab inside your FTP Resource, change your Retries to 5 and your Retry Interval to 20 or 30 or even 60. This means, when you get that error, it will wait "x" time then try again, picking up where it left off. If (after 5 retries) you're still having an issue during transfer, then there will be logged information in your Job Log that will give you more reasons as to why .. if you have the "DEBUG" enabled on the FTP Task you are executing.

The most common issue with FTP/S resources to fail with the "Closed without indication" is the resource is not set to passive and implicit.

Use passive mode on the resource

Set to Implicit SSL on the resource
