I am attempting to run a local ipv6 network and have gone through a number of tutorials, but with limited success. I'm running a server on the router/access point and it is the only device I need to access. Most of the tutorials I've read instruct you how to make an internet addressable ipv6 router which goes beyond my needs and I can't always follow exactly because of this. As far as I can tell everything is setup correctly, I can even see neighbors, but are unable to ping the neighbors I see from the router or the router from a connected device, further attempts at access are similarly futile, http requests and so on.
I have opened a wireshark, and see only DNS and ICMPV6 protocol messages.
The access point is a pi running raspian where I am trying to connect my windows 7 laptop to. I've included a lot of information below because it is all correct as far as I can tell, so I'm sure I'm missing something.
On the access point:

On the windows end device
ipconfig:

From my understanding, if the end device is showing up as a neighbor on the router they should be able to communicate. Now it is showing as a stale connection, but even when in the past it has been listed as REACHABLE, I have been unable to ping it.
