It seems this pool http://18.104.22.168:8080/getting_started does not support Bech32 address. Some poor people are mining to that addresses.
Base on IP it looks pool belongs to devs so maybe worth to fix it.
Thank you for telling me
Jcchian why are you posting link on miner ? Issue is that the Pool is not able to send mined coins to Bech32 address to wallet.
The mining pool tool link has been updated
OK I take it back. It looks pool sent it but it did not arrive into wallet.
With this miner I couldn't mine SOLO for my wallet, but I had a better performance with cpuminer-ryze in rplant's own pool
