Yamaha RX-V673 "access denied" error connecting to server

Exact same problem. Can't access anything reliably (Pandora, Sirius, etc.). Even tried turning off my routers firewall -- still nothing.

Strangely, I can connect to the receiver over IP using my iPad, but not my PC. Not sure if they're related.

I'm also having the same issue has someone solved this?

I contacted Yamaha customer support. We ran through a few checks, although I think the whole setup was working better with the tech over the phone (of course). He seemed to think that it was my router blocking/restricting WAN access. That's somewhat difficult for me to believe because the Yamaha receiver is the ONLY device in my house (I also have multiple iPhones, an iPad, a PS3, two Rokus, two internet TVs, a media server, multiple PCs, a Macbook Air, etc.) that has issues.

I've all but given up.. I just relocated my Bluetooth receiver to the Yamaha to avoid pulling my hair out.

I too have the same problem. Fairly common by the look of it. Anyone out there solved this?

Trust me, I tried everything. I gave the receiver a static IP and put it in the DMZ and tried completely disabling my firewall.. Setting a permament wireless channel... Turning off everything near the router and receiver that could cause interference -- nothing.

Sure, it would work for about 10 minutes, and then suddenly drop. On my iPad, it wouldn't appear as an Airplay-enabled device. Some days it's there, most of the time it's not.

So I went out and bought an Apple TV. It works every time.
