KDL-48W705C doesn't connect to online apps

KDL-48W705C doesn't connect to online apps since yesterday.
I've checked TV for last firmware, changed regional settings (I'm from Ukraine), then made factory reset -- no result. All other apps (browsers, mediaplayer) works fine.
Any ideas?
Thanks.

I solved the problem. My router blocked some requests.
