Hi,

Few things : 
1.  Which version of Agile you are using.
2. Is the isue reproducible to all.
3. Also, while opening the file in Java-client, try to have Java-console. It will give you details about the error.  You can set up the console by opening Java-Control Panel.  Navigate to Advanced tab and Click on the radio button next to “Show Console” 

There are few things you can check : 

1. Check if file-manager server is on or not. 
2. You can log into the file-manager box and try to re-start the Apache tomcat server.

Also, try clearing the browser cache if it is an isolated issue.  Usually does wonders.

Yeah in addition to Pat’s suggestion. You can check if Mixed contents are blocked or not. You can unblock it. For every browser it’s different set of approaches, 

e.g in FF you can do the following : 

1. Go to address bar. Type about : config
2. Click on I understand the risk.
3. Locate security.mixed_content.block_active_content to FALSE by double clicking on it.

The connection between your application server and File Manager has failed.  Even though you already know this (based on the error you got from the Java Client) you can check the status any time using the following URL:  

http://<hostname>:8080/Filemgr/Configuration 

If you were previously able to use these attachment functions – you may just need to restart the Application Server and File Manager.  If there were any recent changes – you might need to check your FM configuration in the Java Client.

Hi,

I checked the filemanager configuration and the Application Server Connection link ending with FSHelper  is showing as Failed while others all are Success.

Have you tried restarting the Application Server and File Manager?
