Port Forwarding Error 31526?

I’m still having this problem.  Like PHubaut, I’ve  verified that my port forwarding works, so all signs point to the MBLD not behaving properly.  I have a hard time believing this would require a RMA, and isn’t something that can be fixed through a firmware update (which is what I think broke it in the first place).

Even with the relay connection, the performance of WD Photos on my iPad and Android phone hasn’t been very good.  Unless I’ve looked at pictures while connected to my local LAN, and they’ve been cached, once I’m on someone else’s LAN (e.g. my in-laws), most pictures won’t show up.
