Hi Albyer,

I’m running Alby Hub on Umbrel and I’m trying to switch from using Umbrel’s LND node to the built‑in LDK node only.

Steps I took:

Closed all LND channels and moved my funds on‑chain.

Uninstalled the Umbrel LND app.

Uninstalled and reinstalled the Alby Hub app from the Umbrel App Store.

Rebooted Umbrel multiple times.

Removed all Docker volumes that looked related to Alby Hub, then reinstalled the app again and rebooted.

Problem:

When I open Alby Hub from the Umbrel UI, the page does not load (“connection was interrupted / server not available”).

The Alby Hub setup wizard (where I would expect to choose the built‑in LDK node) never appears.

Relevant log lines:

AlbyHub v1.21.2

Failed to read LND cert file

Failed to create service error="open /lnd/tls.cert: no such file or directory"

So even after uninstalling LND and cleaning up, Alby Hub still tries to start in a mode where it expects /lnd/tls.cert and immediately crashes, instead of offering the LDK‑only configuration.

Environment:

Umbrel (latest stable at the time of writing)

Alby Hub v1.21.2 (Umbrel app)

LND app uninstalled from Umbrel

Bitcoin Core on Umbrel is running and synced

Could you please:

Confirm how to force Alby Hub on Umbrel to start with a fresh configuration using only the embedded LDK node (no LND), and

Tell me if there is any known issue with v1.21.2 on Umbrel when LND is not installed?

Thanks a lot for your help.
