Mithril is not finding valid hashes, while XMRig works (same pool & wallet)

[Dssall2]

Good afternoon!

I decided to run Mithril again after a couple of months but faced an issue:

The miner starts successfully, CPU load is present, hashes are generated.
However, no valid hashes are found, and pool statistics are not updated.
Tested on the same pool (xmrpooleu) and with the same wallet, but no success.

At the same time, XMRig works fine on the same pool and wallet—valid hashes are found, and statistics update correctly.

I had a theory that maybe the pool or Monero changed the algorithm or hash verification parameters. I went through the code, added debug println!, but after a week of troubleshooting, I couldn't find the cause.

Could you check if this issue reproduces on your side? If needed, I can provide my config.toml.

I wrote you on e-mail if it is more convenient we can discuss there would be glad at least a hint on what goes wrong

Thanks in advance!
