My node can't keep its peers

[Falci]

When I check ThunderHub, it says all my channels (4) are red/inactive. When I check lnd logs, among other things, I see:

CHRE: The chain backend has an insufficient number of connected outbound peers (0 connected, expected minimum is 6) which can be a security issue. Connect to more trusted nodes manually if necessary.

My setup:

• Raspberry Pi 5
• Ubuntu 24.04
• lnd version 0.18.2-beta commit=v0.18.2-beta
• Bitcoin Core version v27.1.0
• Tor version 0.4.8.10.

I opened my router port 9735 and mapped to the Pi's MAC, in case someone tries to connect via clearnet (was it needed?)

CHRE: The chain backend

That's bitcoind. So check your config there and add static (trusted, if you know someone who also runs a node) peers and/or enable clearnet on bitcoind as well.
