Goldshell Mini-DOGE – Red Light / Failed to Startup
Critical (miner is non-functional, hashrate is 0 MH/s, but hardware is usually recoverable)
Critical — Immediate action required
Symptoms
- Front-panel LED is **solid red** from the moment the fan spins up (not blinking red, not red+green together, not amber)
- Fan spins normally; PSU brick hums with no popping; no burnt-electronics smell
- `find.goldshell.com` shows the miner's MAC but no IP, or shows no device at all
- Web UI at `http://<miner-ip>` times out, returns `ERR_CONNECTION_REFUSED`, or loads a blank white page
- If the web UI loads, the dashboard shows `Pool 1: disconnected`, `Pool 2: disconnected`, hashrate `0 MH/s`
- Log shows repeated `pool connect timeout` or `stratum subscribe failed` after a DHCP-assigned IP appears
- Red LED came on immediately after a firmware upgrade — especially one attempted over `WiFi` rather than ethernet
- Miner is on factory firmware (came out of the box red) or on a Goldshell release known to have startup bugs (e.g. `2.1.1`, `2.1.3` on sister BOX devices)
- Miner was recently moved, power-cycled during an update, or lost power mid-upgrade
- `ping <miner-ip>` responds intermittently or not at all
- On Mini-DOGE III+ only: the status page briefly shows `Connecting...` before the LED settles on solid red
- You are trying to connect to a pool other than `Dxpool` or `F2Pool` (`NiceHash`, `ViaBTC`, `Prohashing`, custom stratum) — Goldshell firmware silently rejects many of these
Step-by-Step Fix
True cold boot Expected: LED cycles during boot, settles on green with fan audible If it fails: proceed to Step 2
Direct ethernet to router (skip switches and powerline) Expected: find.goldshell.com sees the miner with IP If no IP appears: jump to Step 7 (network-side) If IP appears but LED stays red: proceed to Step 3
Load http://<miner-ip> in browser Expected: Goldshell login screen (default user: admin, default password: 123456789) If blank page / timeout: filesystem is likely corrupt → Tier 3 SD-card recovery If login works: proceed to Step 4
Check the Miner page for pool status Expected: Pool connected, accepted shares If pools show disconnected: proceed to Step 5
Remove configured pools, save, add a single Dxpool or F2Pool URL Expected: pool connects within 60 seconds, LED transitions to green If still disconnected: proceed to Step 6
Check dashboard ASIC status on Miner page Expected: all ASIC chips listed with non-zero hashrate If ASIC count is wrong / chips missing: hardware → Tier 4 D-Central repair If ASICs all enumerate but no pool connect: network/firewall → Step 7
Isolate network path Expected: laptop on same cable pings pool URL and reaches pool port 3333 If pool unreachable from laptop: ISP / firewall issue, not miner If pool reachable from laptop but not miner: miner firmware → Tier 3 reflash
If red LED persists with no web UI after Tier 3 reflash Expected: fresh firmware boots green If still red: hardware → Tier 4 D-Central repair ```
