Impossible to connect my LND node to my (separate) bitcoin node

[AirHache]

Hello,

I'm trying to connect manage my lnd node and my bitcoin node as 2 separated vm (for disaster recovery efficiency).

Bitcoin is in v28.0 Lnd is in v0.18.3

Both VMs are hosted on the same Proxmox.

Blockchain is fully synced on bitcoin node.

I used sshfs for sharing the /data/bitcoin repository with my lnd node.

Problem : I tried to modify bitcoin.conf and lnd.conf, in order to set-up connection between the 2 servers and having lnd rpc parameters pointing to my bitcoin node, but it fails.

That is, when I run lnd on my lnd node, it goes to "wallet unlocked", but then nothing is happening. Logs file does not say more information.

Did anybody encounter such issue?

You didn't post any error message, so I assume it's the issue with bitcoind v28: #9163 (comment)

it could be linked! I'm going to investigate.
