ADVISORY(8/5/2016) Adding an External File System fails with FileCatalyst Server installed on Linux and Java v8 build 60
Posted by , Last modified by Aly Essa on 05 August 2016 02:41 PM


Attempts to add an External File System (EFS) fails on a FileCatalyst Server installed within a Linux environment with an unable to connect error.  

When you click the Test button from the File Systems tab, a dialog box pops up with the message that file system test failed: Please check that your hostname/endpoint is correct.

If you click Save, a dialog pops up to indicate changes committed to FileCatalyst Server and the External File System appears in the File System list. After a few seconds, it turns red and message appears to indicate that it is not available.


Filecatalyst Server v3.5 and v3.6.

Java v8.0 build 60.

Linux Environment.

Amazon S3 Storage or Azure Blob Storage.


To resolve this issue an update to a more recent version of Java is required. The Java upgrade documentation can be found here:
