Also check the connection between your miner and the mining pool, this may happen when there is a problem connecting to the mining pool.

2. Confirm that your internet and network are stable. Most customers do not know that their network configuration or router settings can cause this error. You can use the Ping button under "Network" and then use "Diagnostics" to ensure that your miner can receive data.
