Question

I have downloaded and configured the Flickr ECL in my Tridion, Mountpoint has been created successfully. when i click the mountpoing, i am getting different error in my local machine and Tridion server.

Error from local machine: WebUI/Models/ECL/Services/General.svc/GetList failed to execute. STATUS (404): Not Found

Error from Tridion installed Machine:Unable to connect to the remote server No connection could be made because the target machine actively refused it.

Check out this useful blogpost from Mark Saunders, after the release of the Flickr ECL Provider, Flickr has made changes to their API URL, and so currently the extension you downloaded will not work as is, but with a small change you can be on your way again:

Update

Keep in mind that the connection to the Flickr APi is created from the CM server, and also that the ECL Provider currently does not take any proxy settings into account which might be required to connect to the internet on that machine.

First thing I would check is if you can access the Flickr API from the CM server, preferably not only in a browser or via a ping in a command prompt, but using some .NET sample code (see http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx)
