Q1.The miner has been shut down due to high-temperature protection being triggered.
— Check whether the ambient temperature is too high (above 35℃).
— Check whether the air inlet and outlet of the fans are blocked (for example, the air inlet and outlet are facing the wall, and there are too many attachments such as dust and catkins).
— Restart at least 10 minutes after the high temperature protection, and observe whether the temperature of the miner is stable after running.

Q2.The new miner cannot obtain an IP address
— Check whether the Ethernet port is plugged and whether the Ethernet status light is on or check the WIFI has been successfully connected.
— Ensure that your miner and your device(phone/computer) are connected to the same network and frequency band.
— Make sure that the miner network setting DHCP is turned on. If you do not confirm, press the “Reset” button for about 10 seconds to restore the factory settings.

Q3.Red light blinks slowly/IP cannot be found/cannot enter the miner dashboard
— Check if your miner and your phone or computer are on the same network and frequency band.
— Check your network. 1) If you use an Ethernet cable, please change the cable or test that the cable is working fine. 2) We suggest changing the network or testing your network using a different device.
— Make sure your router won’t prohibit new IP addresses.
— Make sure there is no antivirus software blocking your visit to https://find.goldshell.com/.
Perform a factory reset: press the reset button for about 10 seconds. (During “reset”, the lights near the IP button will flash together.)

Q4.Firmware upgrade failed
— Symptom 1: After the software progress bar completes the upgrade and the miner restarts, but the miner remains in the original version.
— Solution of Symptom 1: Continue the upgrade and observe if it can be upgraded successfully. If it continues to fail, please contact Goldshell after-sales service
— Symptom 2: The miner restarts during the upgrade process, causing the upgrade to fail, and the miner becomes unresponsive and “bricked”.
— Solution of Symptom 2: please contact Goldshell after-sales service

Q5.Miner is “overheat”/The miner dashboard displays “overheat”
— Restart the miner.
— Make sure there is no other things blocking the air outlet and inlet.
— Make sure the environment is cool, dry and ventilated.
— If you have more than one miner, you can put this miner in a detached room if available.
Check if fans are properly installed and ensure that they are installed in the correct orientation.

Q6.Reject rate is higher than 5%
— Network delay is a major cause of high reject rate.You may try the following steps to resolve this:
Step 1: Restart your miner and keep monitoring it;
Step 2: Check your network connection, switch to a different network, or replace the network cable.
Step 3:Switch to a different pool and make sure the pool matches to the coin you are mining.
