LND 0.18.4 / TOR issue

[AirHache]

Hi,

I installed many times Bitcoin Core + Lnd in the past, however these last days I tried to install v0.18.4-beta, and I'm getting an error which never occured before, linked to Tor configuration.
I'm kinda new to Tor, therefore I'm wondering if anyone could help me to troubleshot the issue I got on LND.

Below are the logs from file .lnd/logs/bitcoin/mainnet/lnd.log :

I already tried to modify /etc/tor/torrc file, for using Port 9051 instead of Default (9050), but I get then another issue on LND.

Anyone can help?

Thank you.

Your Tor node doesn't seem to be started correctly: dial tcp 127.0.0.1:9051: connect: connection refused. Or it's not listening on port 9051. Port 9050 and 9051 are for different purposes, so changing the port numbers won't fix things. So best to check your Tor config and logs.

Hi,
Thank you.

After investigation in /etc/tor/torrc file, I found out that Control Port 9051 seems now to be commented.

Thus i uncommented:

ControlPort 9051
HashedControlPassword HHHHH 
CookieAuthentication 1

LND seems to work fine now.

Thank you for your help!
