This thread is designed around real beginner search intent in Polski. Please share the questions new miners ask most often and the most useful answers about setup, hardware, profitability, pools, solo mining, and safety.
This is more common than people think, especially with new firmware or rushed setup changes.
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.
What helped me most was writing down the exact symptoms before changing anything. Once I compared the dashboard, local logs, and power behavior together, the real cause became much easier to spot.
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.
A practical comparison with real setup details would make this thread much more useful for future readers.
