This discussion in Hrvatski (Croatian) is for beginners who are not ready to waste money. Good replies should explain what to learn first about power, heat, wallets, profitability, firmware, and realistic expectations.
I had a similar situation on a smaller setup and the lesson for me was not to assume profitability or stability from one short test window. Watching behavior over a longer period gave me a more realistic picture.
I ran into this after changing pool settings and thought the machine was the problem. In my case the miner was fine, but the network path was unstable and the shares started coming through only after I fixed DNS and restarted cleanly.
Thanks for posting this. I was trying to figure out the same thing today.
A practical comparison with real setup details would make this thread much more useful for future readers.
It helps a lot when people include what symptoms they saw, what they tested, and what actually changed the result.
This is a strong SEO-style topic because it matches the real questions miners keep asking again and again.
This is exactly the kind of question many new miners search for before they commit money or hardware.
I think the most helpful answers here are the ones that explain what to check first, not just the final fix.
