Deco guest network does not access internet when using internal DNS server (i.e pi-hole)

So i installed pi-hole DNS server in my home NAS (Synology D920, if it's relevant).
Deco does not allow to change the DNS setup under "internet connection" tab, to internal address, and asks me to update the DNS address under DHCP server, at its DNS field.
So I updated the new local DNS address there.
Primary network works excellent with local pi-hole DNS.
However guest network can't access the internet. I receive DNS resolution error page. when I deleted the local DNS address under DHCP server tab in Deco app, the system resumed working with the ISP DNS, and guest network works properly.
I don't think it's a pi-hole issue, as its server (NAS) is connected with a wire to the X55 DECO.
any ideas?
thanks.
