[Cant select server to upgrade from 6.x to 7.0]

Hello,

I installed eset 6.x version on a domain controller, i wanted after this to update. When i try to upgrade components from client tasks i accept terms and i have to choose server, when i press to choose server it shows nothing so i cannot upgrade. (i checked license and its ok)

I tried to restart services, change port to tomcat (reinstall tomcat) nothing worked so far.
