Milan,
I had seen this - https://gitlab.com/cryptsetup/cryptsetup/issues/112. But it did not click to me - since the key reported as 256 bits in "status" output.
Thanks for the pointer. I will try out your solution.

Your keyfile is only 16 bytes long, you need 32 bytes for 256bit key.
(There was an bug in cryptsetup 1.2.0 where this was not reported and rest
of key was zeroed.)
Try to add these zeroes to your keyfile and repeat.
(Like dd if=/dev/zero of=<keyfile> seek=16 bs=1 count=16 conv=notrunc )
But note your key is half-zeroed (since the beginning!).
