This thread is designed around real beginner search intent in Important Announcements. Please share the questions new miners ask most often and the most useful answers about setup, hardware, profitability, pools, solo mining, and safety.
I had something similar happen and the fix was much simpler than I expected.
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.
For anyone still troubleshooting this, the most useful sequence I found was: confirm the wallet and worker format first, then verify the stratum target, then check miner logs, then look at temperature and uptime, and only after that start changing firmware or network settings. Doing it in a clean order saved me a lot of time because I stopped guessing and started isolating the real problem.

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.
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.
