# Troubleshooting & FAQ

### <mark style="color:$primary;">Common Troubleshooting</mark>

#### <mark style="color:$warning;">1. I have 0 Peers" in the logs</mark>

Your firewall is absolutely blocking the connections. Please re-visit the Network & Firewall step. Ensure ports `30303`, `13000`, and `12000` are open internally (e.g., UFW) AND externally on your Cloud Provider's website (Security Groups/VPC).

#### <mark style="color:$warning;">2. Sync Warnings (Execution client is not syncing)</mark>

During the very first day, your node must download the entire history of the blockchain. You will see errors like "Beacon node is not respecting the follow distance" or "No responsive beacon node found". This is perfectly normal! Be patient. Once the history sync reaches 100%, these errors will vanish automatically.

#### <mark style="color:$warning;">3. "Waiting for deposit" OR "No active keys"</mark>

Your node is running perfectly! However, the network either hasn't seen your 32,000 ZUG deposit yet, or your keys are in a queue waiting to be activated. If you haven't made your deposit transaction yet, head over to the Launchpad to complete it. Otherwise, simply wait for the network to activate your node (this can take up to a few hours depending on the queue).
