Same problem here. Same resource. If we open the link to the resource as described in the error-message the bannerlogo is downloaded so the banner is there but cant be loaded. Its sporadically happening as well. Worked for myself whole day yesterday and this morning, then I got the error. And after lunch the error was gone again.

We had the same problem a few days ago. It happened sporadically for us also and just a few users was affected. Could anyone from IFS make a comment on this issue, would be helpful?
