Description:
============
BusinessConnect (BC) fails to pull files from the SSHFTP server after getting a 550 signal. Previously, it worked perfectly while getting a 220 ok signal.

Environment:
==========
Applicable to all the environments.

Symptoms:
=========
BC stops pulling files from the SSHFTP server and continually gets a 550 signal from the server. A 550 signal means either the files are non-existent or access to that file is denied.

Cause:
======
There are situations in which the SSH tunnel gets corrupted. BC sees the tunnel and thinks its a legitimate tunnel and tries to pull the files even though the tunnel has been corrupted. So BC will get a 550 signal back and will fail to get the files from this point on.

Resolution:
=========
The resolution for this condition is to break the corrupted tunnel and create a new tunnel instance. This can be done by setting a timeout for the tunnel in the in-active state. Log into the admin GUI, and navigate to BUSINESS CONNECT -> SYSTEM SETTINGS -&gtINSTALLED PROTOCOLS -> BC SERVER and set the "bc.sshftp.cache.tunnel " property to a value in minutes. This would create a new instance of the tunnel after the timeout.
