t-rex v.0.25.8, "Can't find nonce with device"

[PSLLSP]

t-rex v.0.25.8, HiveOS, GTX1660

After upgrade to t-rex v.0.25.8, I cannot dual mine ETH+ALPH. Version t-rex v.0.25.6 was OK. My HiveOS rig has only two cards GTX1660.

t-rex v.0.25.8, hits an error:

What parameters are you launching T-Rex with? Open HiveOS shell, navigate to /hive/miners/t-rex/0.25.8 and run ./t-rex -a ethash --dual-algo blake3 -o stratum+tcp://eth.2miners.com:2020 -u 0x1f75eccd8fbddf057495b96669ac15f8e296c2cd -p x -w rig0 --url2 stratum+tcp://de.alephium.herominers.com:1199 --user2 1qUuxVuXN2Pk4nnYTbL4qihjLWyRkVMQVYQDAajCcuPq --pass2 x. Is it working? If so, there's something wrong with your flightsheet config.

[PSLLSP]

Your command works. But HiveOS uses config.json, something like ./t-rex -c config.json. I configured an extra option "lhr-autotune-mode": "off", the rest was generated by HiveOS from flightsheet.

This is config.json file, it doesn't work with v0.25.8:

[trexminer]

You need to use "dual-algo": "blake3" instead of "lhr-algo": "blake3", and you don't need "lhr-tune": "45" because your cards are not LHR.

I tried to changes in system upgrade and update but nothing happened at the end I go to overclocking settings then choose popular present and take one of that settings and changed it to overclocking after that it works normally in hive os
