Troubleshooting Advanced Mining Issues
Even experienced miners encounter issues. This final lesson covers common advanced problems and how to solve them, so you can keep your Qubic mining operation running smoothly.
Authentication Failed / Access Token Errors
If your miner’s log or console shows an error like “ERROR AUTHENTICATION FAILED”, it means the pool rejected your token or address . This can happen if your access token expired or was revoked, or if you mistyped your wallet address. Solution: If you’re using an access token (for a Qubic.li account), log into the pool website and generate a new token, then update your miner config . If you’re mining with just a wallet address (no login), double-check that the address is correct and corresponds to an actual Qubic wallet (addresses start with qubic_...). Also check your internet connection – occasionally a connection issue can cause auth errors if the miner can’t reach the pool reliably . Once corrected, restart the miner.
GPU Not Engaging (or GPU errors)
If you have a GPU but notice it’s not being utilized (e.g., no speedup over CPU-only, or an error loading CUDA/OpenCL), check drivers and OS support.
Transition note: GPU troubleshooting is temporary;.
AMD GPU not mining
Availability of AMD GPU trainers can vary by epoch. Transition note:
Mining Slows Down Unexpectedly
Investigate thermal throttling, power plans/governors, background processes, or other software using resources. Keep rigs clean and headless where possible.
Miner Crashes or Exits
Check the log/ folder for errors. Reduce threads if memory pressure is high, or set a more compatible cpuVersion (e.g., AVX2) if you forced an unsupported path. Ensure dependencies (.NET runtime, VC++ redists) are installed. If needed, reset appsettings.json and re-download trainers.
“AVX not working” issue
If your CPU supports AVX2/AVX-512 but the miner isn’t using it, override with “cpuVersion” in appsettings.json and restart. Target AVX-512 for long-term compliance.
Idle but No XMR Mining
If you disabled XMR fallback, idle periods won’t earn. If unintended, ensure xmrSettings.disable is false and firewall allows the XMR connection. Note: Fallback switching is built-in; external scripts are not required.
Strange Hashrate or score reporting
Pool UIs can lag. Restart miner/system if needed and check community updates.
