Thumbnails in CMO not working after upgrade
Hi Henrik, no changes in configuration of thumbnails? This just started after upgrading to the new package release last week?

Hey Richly
No, this has been all the time since we upgraded to 7.5 a couple of month ago, but I have not started to use it until now because of the MVC-bug

I've seen a similar error in the past, but couldn't quite get a firm resolution on it. One guess is *could* be some security issue - http://world.episerver.com/Documentation/Items/Installation-Instructions/EPiServer-CMO/CMO-20/Configuring-the-Thumbnail-Service-on-Windows-Service-2008-R2/.

After we upgraded to EPiServer 7.5 and CMO 7.5 (I have updated to the latest version released last week) we can not see any thumbnails in the A/B-section anymore.
The error we get in the logs are:
ERROR EPiServer.Cmo.Cms.ThumbnailHandler.CmoThumbnailHandler.TryRequestPageThumbnail: Unexpected error during communication with remote thumbnail service
System.ArgumentException: Parameter not valid.
