another piece of information that I've seen requested

In config interface wan6
Try changing
option ifname 'eth0'
to
option ifname '@wan'
//edit
I have the message odhcp6c[4624]: Failed to send RS (Address not available) in my log too.
But ipv6 works fine.
However a few days ago prefix delegation stopped working.
And prefix delegation works again.
Maybe it has to do in which order the interfaces are brought up.
Or because the modem interface has static IP configuration and therefore defaults to force_link 1?
(and some things are not triggered because of that?)
The message: Failed to send RS (Address not available) maybe appears because odhcp6c is started too early.
I tried several variations on the advice from @shm0 and @anon50098793 with no change. I'm assuming that my ISP has a fault or stopped IPv6 service - will try to find some route to report this to them
now working, was an issue with the fibre terminal box supplied by my ISP. They reset it remotely and IPv6 started working. Thank you for the assistance
