Have you tried accessing the REST API on default port 8080? As far as I know that forwards all requests to gRPC.

That's how I've setup Zaprite for users to access their own nodes.

It works for Tor and also on clearnet (ex. Voltage) nodes using LND.

But ultimately it could be a docker issue blocking incoming traffic over certain ports.

Publicly exposing lnd's gRPC port from within Umbrel?

- Umbrel uses default port 8080
- MyNode uses port 10080
(both require https)
