Hashrate Drop

Possible causes of hashrate drops in HashCore Proxy and how to fix them.

If you notice a decrease in hashrate, it may be related to a reduction in the number of connections. There can be several causes:

1. Primary Pool Unavailable, No Backup Configured

If the primary pool stops responding and no backup is set — the proxy cannot route hashrate anywhere and disconnects miners. Always configure at least one backup pool in each proxy group, preferably two.

2. Proxy Lost Internet Connection

A brief loss of connection to the pool causes miner connections to drop. Some miner firmware does not reconnect immediately. If the issue occurs regularly — check the internet connection stability on the server running HashCore Proxy.

3. Miners Lost Connection to Proxy

HashCore Proxy and miners must be on the same local network. Connection status is visible in Grafana: a drop in Downstream connection count indicates miners have disconnected.

Backup pools are the main protection against hashrate loss
Whatever the cause of the hashrate drop — always configure backup pools. This is the only way to prevent hashrate loss when the primary pool has issues.
