When the Antminer Z9 kernel log shows no serves could be used, you can troubleshoot according to the following actions.
Troubleshooting:
When there is a failure on the kernel log, it may be caused by a mining pool failure, you may have entered the wrong URL during the connection process, you forgot to add a port, or you did not set up a worker. It is recommended that miners replace the ZEC mining pool before running the miner.
For specific connection instructions, please refer to the Antminer Z9 Manual.
