An incompatible browser or a browser with excessive cache
Use various browsers to test as a solution; we suggest using Firefox or Google Chrome. If clearing the cache doesn’t work, try using a different computer or laptop.
The password is wrong
When the default password has been altered, this happens.
Solution: enter the correct password or reset the miner and use default password “root”.
Conflict MAC address
The two miners have identical MAC addresses, which results in matching IP addresses. Alternately, the two miners will be abnormal.
Solution: Attempt to upgrade the miner to the most recent Antminer Z15 firmware version, which S9i can do by using firmware version fix_mac.tar.gz. to fix the duplicate MAC issue.
Conflict IP address
One of the miners obtains a dynamic IP address via DHCP, which is incompatible with the other miner’s static configuration of the same IP address.
To find a new IP address, employ DHCP.
Network anomaly
Ping the miner’s IP address to find a solution. If it can’t be pinged, check and make sure:
- the router configuration is normal;
- the DHCP server is enabled;
- assignable IP addresses in the DHCP address pool is set in a proper range;
- the computer network port, the miner’s network port, and the switch network port indicator are normal.
You can try restarting your computer and your network hardware. Check the Ethernet cable, the switch port, the switch or router, and all of the above.
The control board has an issue
Solution: a. reset the control board; b. use the SD card to recover the program; c. replace with a good known one.
The miner has been hacked
