I discovered it from the end of December. Now i checked it while loged in and loged out. Moreover i asked my company's system administrator to check this on his computer with different brousers. It doesn't work there also. Is there a way to slove this problem?
I would usually ask these questions:
It seems you've tried these. Is it possible there are restrictions imposed by your ISP?
Thank you for your reply. The problem still exist. I can see some of previews, but others don't.
It seems the problem is at Adobe side, because some previews have link like this:
They work well.
But some previews have link started with as1.ftsdn.net and they don't work.
If i copy the link, past it in brouser and manually change 'as1' to 'as2', it shows me write image.
The problem still may ly on your side, if one domain gets blocked and the other does not by your ISP or your own firewall.
