Need help setting up your Bitaxe or Nerdminer?
Read Setup Tutorials on our Blog🛠️ Common Errors & Troubleshooting
1. "Unauthorized Worker" / IP Ban
Your miner is getting 10s temporary bans in our logs.
Cause: Using a prefix like BTC: or bitcoin:.
Fix: Use ONLY your clean wallet address as username.
BTC:bc1qxs2j...
bc1qxs2j...
2. Difficulty Too High / No Shares
Miner connected but 0 Shares on dashboard.
Cause: Wrong port for your hardware power.
Fix: Match your device to the right port: BTC SOLO
- Bitaxe (1-2 TH/s): Use Port 6616 or 6611 (TLS)
- NerQaxe (5-10 TH/s): Use Port 6617 or 6613 (TLS)
- S21-S19 (10-500 TH/s): Use Port 6618 or 6615 (TLS)
Fix: Match your device to the right port: BTC PPLNS
- Bitaxe (1-2 TH/s): Use Port 6626 or 6621 (TLS)
- NerQaxe (5-10 TH/s): Use Port 6627 or 6623 (TLS)
- S21-S19 (10-500 TH/s): Use Port 6628 or 6625 (TLS)
3. SSL/TLS Handshake Failed
Fix: If using stratum+ssl://, make sure to use our dedicated TLS ports (BTC SOLO: 6611, 6613, 6615; BTC PPLNS: 6621, 6623, 6625; BCH SOLO: 7711, 7713, 7715; BCH PPLNS: 7721, 7723, 7725). Our German node supports full TLS 1.2/1.3 for maximum security.

4. Duplicate Shares (normal on Bitaxe / NerdQaxe)
Your miner shows 2–4% "duplicate shares"? No worries — this is a well-known behavior of the Bitaxe / NerdQaxe firmware (ESP-Miner), not a pool issue.
Cause: On job transitions the firmware occasionally resubmits the same share. This happens on EVERY pool (public-pool, ckpool, Ocean …).
Fix: Nothing to do. Your rewards and block chance are NOT affected — the pool correctly detects and ignores duplicates. Your miner works perfectly. ✅
