Service onions unreachable but Start9 system onion works. Running StartOS 0.3.5-1 with LND 0.20.1 and Bitcoin Core. Trying to connect LND to an external Railway backend over Tor.

The problem: LND's Control Interface onion address is unreachable externally.

What works:

• Start9 system onion loads fine in Tor Browser
• Bitcoin Core has 12 active peer connections over Tor (outbound)
• LND is Running and Synced to chain and graph
• curl via SOCKS5 to DuckDuckGo onion works fine

What doesn't work:

• curl via SOCKS5 to LND onion returns SOCKS5 error 5
• Bitcoin Core Peer Interface onion also unreachable
• Tor Browser shows "Unable to connect" for all service onions

What I've tried:

• Reset Tor without wipe state (multiple times)
• Reset Tor with wipe state
• Full system restart
• Turned off "Use Tor for all traffic" and "Stream Isolation" in LND config
• Previously saw overloaded guard node warning — fixed with wipe state reset

Conclusion: Start9's own hidden service publishes fine, but none of the installed service hidden services (LND, Bitcoin Core) are reachable from outside. Tor outbound works perfectly.

Has anyone seen service hidden services not publishing on Start9 while the system onion works? Any ideas what could cause this?
