I use the new k2 component now. Minimum every second article link is bad. When i put the link in the hootsuite post or facebook always come out the message: Check out this link.
Now minimum every second article its same. But i think more. So this time i open again the article and i make short url and save again. This time is good. But this to much extra job now every day.

You have any idea?

Is there a link to your site?

Try this: hellourban.com/index.php/erdekessegek2/item/4873-vilagmeretuve-akarjak-tenni-a-legismertebb-magyar-markat

This one today from all. Today all link bad.

Does Hootsuite use OG or any other protoco, since this is a commercial product, I do not have access to it, neither is Hootsuite integration supported by us.

This is most likely a server issue, where their crawler cannot access your links.

On the other hand, on FB it is working fine:
