WSUS clients on remote site do not see any update

I've got a WSUS 3SP2 with all patchs on Windows 2008 R2. It updates all servers. all works but servers 2012R2 on a remote site.

All others Win2012R2 on other sites works.

In the site which have issue, there's only 3 2012R2 servers. There are seen by WSUS console, and they can send report. When i clic link to update from win update, it works too.

Here 's the windowsupdate.log
