Finally it's working!
There were different issues. First of all the bindings of bitcoind services must be on 0.0.0.0 if not external IP cannot connect.
Also, there was a traffic filtering on the bitcoin core firewall and it was blocking LND traffic.

After changing some config as binding to 0.0.0.0 and listening to 0.0.0.0/0 on bitcoin.conf now I get a different error:
Code:

At very least, number on verificationprogress is just estimation and one of Bitcoin Core member said there's no problem if it's slightly below 1.0[1]. It's proven by 0.9999983770795251 doesn't refer to total of verified block since the value equal to 6249989856747 / 6250000000000 [2].

Yes, I absolutely discard that as the issue. I think there's some network config issue on bitcoin.conf and lnd.conf files but I'm unable to see it.
I've modified rpcallowip parameter to 0.0.0.0/0 but still not working :/
If I just wait I get the following message on LND:

With a quick search on the Internet, I found that this could be because Core is not completely sync but it's:
Checking mempool.space 809706 is the last block.
Code:
{
"version": 220000,
"blocks": 809706,
"headers": 809706,
"verificationprogress": 0.9999983770795251,
....

Hi,
I'm trying to connect my LND node to my Core, both on different machines, but my LND is stucked after unlocking the wallet and I cannot make RPC calls as it shows the following error:
Error from lnd side:
With a quick search on the Internet, I found that this could be because Core is not completely sync but it's:

The bitcoin.conf and lnd.conf are the following ones:
