Did I get this right: This coin does not use plain Argon2, it's a variant with Scrypt-Jane added?

If so, it explains why stratum is rejecting all the found blocks.

This coin would get a great hashrate pointed on the chain if the algo is plain Argon2. To make this clear, I'm gladly hosting a pool if a solution is found for the mining algorithm, stratum implementation of your algo or change the algo.
