❓ Frequently Asked Questions (FAQ) ​

🏠 Documentation Hub > Troubleshooting > FAQ

A: We strongly recommend NodeLink:

  1. Zero Java Requirement: Built entirely in Node.js (v22+).
  2. Native Moonlink.js Synergy: Moonlink.js provides native, seamless compatibility with NodeLink.
  3. Built-in Sources: Multi-source support (YouTube, Spotify, Apple Music, Deezer, SoundCloud) is built directly into NodeLink without hunting down separate Java plugins.
  4. Lower Resource Usage: Uses ~80 MB RAM compared to Lavalink's ~512 MB – 1 GB Java heap.

Q2: Why is music buffering or skipping in voice channels? ​

A: Voice audio stuttering is almost always related to:

  1. Audio Server Location: Ensure your NodeLink or Lavalink node is hosted in a region close to your Discord server's voice region (e.g. US-East, Europe).
  2. CPU Starvation: If hosting the audio server and the bot on a 1 vCPU machine, high traffic can cause frame drops. Increase CPU allocations.
  3. Buffer Duration: In config.js or application.yml, ensure buffer duration is at least 5000ms.

Q3: Why are YouTube searches returning no results or 429 errors? ​

A: YouTube frequently rate-limits datacenter IPs (AWS, DigitalOcean, Hetzner, OVH):

  • In NodeLink, YouTube extractors are continuously maintained.
  • In Lavalink, ensure you have installed the youtube-plugin (v1.11.4+) in application.yml.
  • Alternatively, set defaultPlatform: "spotify" or "soundcloud" in config.reverb.js.

Q4: How do I change the default bot prefix? ​

A:

  • Globally: Change bot.prefix in config.reverb.js (default: "r!").
  • Per Server: Any administrator can run r!setprefix <new_prefix> (e.g. r!setprefix ?).
  • Slash commands (/play, /skip, etc.) are also always available regardless of prefix.

Q5: Why does the bot leave the voice channel after a few minutes? ​

A: Reverb has an automated idle detector (autoDestroyOnIdle: true with a 5-minute timeout). If no tracks are played or everyone leaves the voice channel, Reverb disconnects to save server resources. To keep Reverb in voice permanently, enable 24/7 Mode:

text
r!247
# or
/247

Q6: Can I run Reverb without installing MongoDB or PostgreSQL? ​

A:Yes! Reverb defaults to SQLite (better-sqlite3), which stores all data in a local file at ./data/reverb.sqlite without requiring any database server installation.

Q7: Is there an official hosted Reverb bot, or do I have to self-host? ​

A: You do not need to self-host! You can invite the Official Reverb Bot directly to your server:
