If the S9 doesn't have hardware version or BMMiner, it means the mining program has not started yet.
First, please confirm that your internet connection is stable. Network configurations or security settings in the router can cause this error.
Second, please check the pool URL in the miner configuration page very carefully. Make sure you've entered three different stratum servers. Any error, including spaces, can cause this error.
Third, please read the kernel log, if it shows "Fatal Error: some Fan lost or Fan speed low", the fan might have issue. Please replace with a good known fan to test.
If all the steps above can't solve your problem, please carefully read and follow these instructions to create a Repair ticket and ship the whole miner back to us for repair: https://shop-repair.bitmain.com/user/workOrderGuide
