[Kea-users] unable to parse the opaque data tuple

[Chaigneau, Nicolas]

Kea doesn't like what's in your DHCP packet.

Can you upload the network capture somewhere so we can have a look ?

I have tested this client in a number of different configurations in an attempt to remove any other influences, and I keep getting the same error.  I have also tested against both Kea 1.2 and 1.3.  Other clients/devices work in the same configuration.
