The ubios-udapi-server process! That's a fascinating one. Common Issues & Troubleshooting | Problem | Likely
- Never expose ubios-udapi-server directly to the internet. Use a VPN (Teleport or WireGuard) to access your console remotely.
- Rotate API keys quarterly. If a key is compromised, revoke it immediately in the UniFi settings.
- Use read-only keys where possible. Ubiquiti does not fully support scope-limited keys yet, so protect write-capable keys strictly.
- Monitor the audit logs. Check
/var/log/messageson the UDM for all API access attempts.
