TrueCommand behind Traefik reverse proxy

TrueCommand
1

I’m having a hard time adding systems to TrueCommand. I’m running TrueCommand behind a traefik rev proxy. Everything else seems to be working fine. Any ideas?

@BooMShanKerX I believe the issue is coming from a bug in 3.2.0 related to recreating the websocket connection recreation to the TrueNAS when using the versioned API, blocking the edit API, which is causing a timeout from Traefik due to a timeout mismatch (1min for Traefik, 2min for TrueCommand), resulting in a 502 before a response is returned from TrueCommand.

Could you one of these options?

  • Use the “legacy client” under API Version instead of “v25.10”
  • Pull docker pull ghcr.io/ixsystems/truecommand:latest and see if you can connect on the latest version (3.3.0, to be released officially in a couple of weeks)

Also make sure the TrueNAS is reachable from within the TrueCommand container.

Updating to 3.3.0 did resolve the issue. Thank you.
