What domain I must open to unblock LG blu-ray player Internet access?

[yf-home]

I have LG BD670 bluray player. When I turn opendns filtering off, it accesses Internet ok. When I turn opendns filtering on, it doesn't access Internet at all: on the Connection Status screen it says, Network is not connected. Apparently, I must open some domain that the player uses for network operation. But I cannot figure out what that domain is. LG customer support is of no help. Can somebody on this forum help? I looked up the log of blocked domains in opendns but the log is too long and I don't see an obvious choice.

Here are the OpenDNS experts, unfortunately not the LG BD670 bluray player experts.  These must be somewhere else...

Q: How are you turning off filtering? If at the Dashboard, I would look for the LG experts first.
