My Geth is throwing errors and not syncing
A common cause of Geth's errors is an improper shutdown, for instance, due to power outage, or not enough time for a graceful process exit as geth writes data to disk. As a permanent fix for the latter case, you'll want to increase your systemd service's `TimeoutStopSec` value to at least `300`.
To fix, you can [resync Geth](https://app.gitbook.com/o/5TLAFycQGS1YA3kIVVOf/s/KnJhWg57YoZq2MPfatKE/\~/changes/57/tutorials/resync-geth).
Running network-wide Pihole? My node is experiencing DNS issues.
By Pihole's default settings, DNS rate limiting blocks any clients with >1000 queries per 60 seconds.
To fix, either increase the queries limit value or exclude your node from Pihole's DNS.
