LN+ App — Tor Hidden Service Descriptor Upload Failing (0 Inbound .onion Connections)

Environment:

Umbrel node (home server)
App: Lightning Network+ (LN+)
Tor version in LN+ container: 0.4.7.8

Issue:
The LN+ app's dedicated tor_server-1 container has been running continuously for 6+ days but reports 0 v3 INTRODUCE2 cells at every 6-hour heartbeat. The app's .onion address is not reachable remotely.

Root Cause (from container logs):
Repeated circuit timeout failures specifically on hidden service descriptor upload circuits:

     No circuits are opened. Relaxed timeout for circuit X
     (a Hidden service: Uploading HS descriptor 4-hop circuit
     in state doing handshakes with channel state open)

No circuits are opened. Relaxed timeout for circuit X(a Hidden service: Uploading HS descriptor 4-hop circuitin state doing handshakes with channel state open)
The .onion descriptor is never successfully published to the Tor directory.

What is NOT affected:

-System-level Tor (Bitcoin node, LND) is fully functional
-Channel forwards are working normally
-LN+ app is accessible locally on the LAN
-Additional observations:

Worth noting:
-LN+ API authentication not working with Thunderhub generation

Recurring HTTP 404 errors fetching authority key certificates from 109.70.100.246:9040 — same three relay fingerprints — persisting across 6 days
Tor 0.4.7.8 in the LN+ container is outdated (current stable: 0.4.8.x)
App restarted May 19 ~09:00 UTC — bootstrapped to 100% in 15 seconds — awaiting confirmation of descriptor upload success

Request:

Update Tor in the LN+ Docker container to current stable
Confirm torrc has correct HiddenServiceDir and port mapping
Advise on the recurring 404s against those three authority fingerprints
