Just some info.
Draytek routers that have built in VDSL need a specific setting enabled or you end up with an error saying "No Response from Server Side"
Check username and password is correct in The WAN>Internet Access> WAN1 (Details page)
WAN>General Setup Click on WAN1 and Check that VLAN Tag insertion (VDSL2) is set to enable, Set a value of “101″ in the Tag Value and Priority of “0″
Hope this helps someone.
