If an ETHF or ETHW miner encounters frequent offline statuses it is likely because of low hashrate issues or the miner did not submit its shares to the pool in time. When the pool does not receive a calculation result from the miner in 10 minutes, it will trigger an offline notification. No further action is required if the miner goes offline as the mining tool will automatically reconnect to the pool.
In such situations, there is no better solution except increasing the hashrate by adding more graphic cards to the miner. Usually, if a single miner’s hashrate reaches 120MH/s, the miner will submit shares more frequently and steadily which will greatly improve the success of the miner’s efficiency.
