Synology Bitwarden_rs Websocket Setup

Below steps allow you to setup Websocket support for your Bitwarden_rs installation running on Synology Diskstation. You can do all steps using the GUI so there is no SSH Access needed.

Prerequisites

• Working HTTPS Reverse proxy Setup (Control Panel -> Application Portal -> Reverse Proxy)
• Set Enviourment Variable WEBSOCKET_ENABLED=true in your Bitwarden container and expose the container port 3012 to a local port, in my case 5556.

Upload script

1. Download enable_ws.sh
2. Upload the script "enable_ws.sh" onto your Diskstation. I would recommand putting it in your Bitwarden directory. In my case /volume1/docker/bitwarden

Create scheduled Task

Control Panel -> Task Scheduler -> Create -> Scheduled Task -> User-defined Script

Make sure to amend the command according to your setup.

• /volume1/docker/bitwarden/enable_ws.sh = Full path to previously uploaded script
• vault.example.com = Hostname of your Bitwarden_rs as configured in the Reverse Proxy
• 5555 = Exposed ROCKET_PORT by Docker (The same as in your Reverse Proxy setup)
• 5556 = Exposed WEBSOCKET_PORT by Docker

Run Command (My example):

bash /volume1/docker/bitwarden/enable_ws.sh vault.example.com 5555 5556

  General Settings
      Task -> Enable BW WS
      User -> root
      Enabled -> Tick
  Schedule
      Run on the following days -> Daily
      Frequency -> Every hour
  Task Settings:
      (Optional) Enable Notifications
      Run Command: <Paste Command Crafted Above> 

Save and run the new task by selecting Run. Login into your Webvault and confirm in your web browsers developer console that the connection to wss:// succeded.

Hey I'm using the latest script posted above and now the sync works fine for me on all devices. But smtp settings for mail sendings has only errors now. could this proxy stuff be the cause for that problem? Because I know the mail feature worked well for me time ago.

Hi,
Script doesn't work for me...
DSM 7.1.1-42962
Docker 20.10.3-1308
Script executes ok, but no change I still get status.Websocket connection failed, "there was an error in the transport".
Anyone has any pointer ?
Thanks

Edit : Solved ! It was my adblocker (adguard) that was at fault ! I now have sync functionnning on my devices, so it's good !
I'm still seing that error in chrome on PC, but as long as my phone is synced it doesn"t matter.
Thanks a lot for the script
