Service won't connect to Mumble

[mwllgr]

Hi,

the bridge is not connecting to my Mumble server and I haven't figured out why, yet. I am using the following docker-compose:

services:

  # Mumble server

  murmur:
    container_name: murmur
    image: mumblevoip/mumble-server:latest
    restart: unless-stopped
    ports:
      - "64738:64738/tcp"
      - "64738:64738/udp"
    environment:
       MUMBLE_CONFIG_SERVER_PASSWORD: "pass123"
       MUMBLE_CONFIG_WELCOME_TEXT: "Mumble Server"
       MUMBLE_CONFIG_USERS: "10"
       MUMBLE_CONFIG_BANDWIDTH: "128000"
       MUMBLE_CONFIG_OPUSTHRESHOLD: "0"
    volumes:
      - murmur:/data

  # Mumble-to-Discord bridge

  discord_bridge:
    container_name: murmur_discord
    image: stieneee/mumble-discord-bridge:next
    restart: unless-stopped
    environment:
      DEBUG: "9999"
      MUMBLE_ADDRESS: murmur
      MUMBLE_PASSWORD: pass123
      MUMBLE_INSECURE: "true"
      MUMBLE_USERNAME: Discord
      MUMBLE_CHANNEL: Root
      MODE: "auto"
      DISCORD_TOKEN: "xxxx"
      DISCORD_GID: "108205103000xxxxxxx"
      DISCORD_CID: "108205103000xxxxxxx"
      DISCORD_COMMAND: "phone"
      DISCORD_DISABLE_BOT_STATUS: "true"
    depends_on:
      - murmur

Are there any known issues as of right now? Tried the latest and the next tag of the image. The bot joins the Discord voice channel but never even logs any attempt of connecting to Mumble.

So some debugging in internal/bridge/bridge.go:

        // DISCORD Connect Voice
        log.Println("Attempting to join Discord voice channel")
        log.Println("1")

        if b.DiscordChannelID == "" {
                log.Println("Tried to start bridge but no Discord channel specified")
                return
        }
        log.Println("2")
        b.DiscordVoice, err = b.DiscordSession.ChannelVoiceJoin(b.BridgeConfig.GID, b.DiscordChannelID, false, false)
        log.Println("3")

Here, my log never prints out 3. Never done anything in Go so I don't really know how to continue here:

Woah, my bad! Three hours of debugging to find out that I forgot a firewall rule - only the default HTTPS (443) TCP/UDP port was allowed (outgoing), so it couldn't connect to Discord's voice service.

Closing this ._.
