Several issues with Bitcoin Core 0.20.1

Hello.

First of all:

Bitcoin Client Software and Version Number: Bitcoin Core RPC client version v0.20.1
Operating System: Debian Buster
System Hardware Specs: 128 GB SS + 1TB Western Digital + 16Gb Ram + i7-3740QM
Description of Problem: Several issues/questions. Will describe them below
Any Related Addresses: n/a
Any Related Transaction IDs: n/a
Screenshot of the problem: n/a (running it from the command line)
Log Files from the Bitcoin Client: bitcoin.conf

The first issue is related to connecting the node via Tor services.
I'll paste here my configurations and will past some log output so that the issue can be better understood (my wording may not be the best).

So, about configs:

In bitcoin.conf I have (among other lines not related with networking):

Code:

proxy=127.0.0.1:9005
listen=1
bind=127.0.0.1
externalip=my.onion.address.onion
onlynet=onion
port=8333
torcontrol=127.0.0.1:9501
onion=127.0.0.1:9005

In /etc/tor/torrc I have (among other lines that were already there:

Code:

SOCKSPort 9005
ControlPort 9501

HiddenServiceDir /var/lib/tor/bitcoin-service/
HiddenServicePort 8333 127.0.0.1:8333
HiddenServiceVersion 3

There is another file that could potentially create confusion, but all lines there matches the ones here. Other than that, in /usr/share/tor/, I have:

Code:

CookieAuthentication 1
CookieAuthFileGroupReadable 1
CookieAuthFile /run/tor/control.authcookie

And I think that's all. The aemon starts normally and I think it connects to the internet via Tor.

Now, 2 issues eventually related to this, that might be due to some wrong configuration:

1 - When we issue bitcoin-cli getnetworkinfo we get a json output in which one of the field is score. The issue is that this filed value never raises as it was supposed to raise with time the node has been online. It's fixed at 4. This value used to increase in the past. I remember that the longer the node uptime, the higher this value used to be. Since this is a parameter that kind of measures the connectivity between nodes, I'm not sure this should be a concern or not.

2 - After some time, the node outputs some messages like the ones below:

2020-10-10T17:18:02Z Socks5() connect to t25hnyuffgirnma2.onion:8333 failed: connection refused
2020-10-10T17:22:41Z Socks5() connect to wzbll26zuafefpq2.onion:8333 failed: host unreachable
2020-10-10T17:23:06Z Socks5() connect to wzbll26zuafefpq2.onion:8333 failed: host unreachable
2020-10-10T17:23:16Z Socks5() connect to wzbll26zuafefpq2.onion:8333 failed: host unreachable
2020-10-10T17:23:21Z Socks5() connect to wzbll26zuafefpq2.onion:8333 failed: host unreachable

Is this on my side or on other nodes/peers side? Is this due to my Tor and node configuration?

There are also messages of successful connections, I guess:

If I issue the command bitcoin-cli getblockchaininfo I get the following:

Code:

"headers": 652125,
"bestblockhash": "000000000000000000080ca212557b350a253a4992989b12838d9bd22804314e",

},

}

And bitcoin-cli getnetworkinfo

Code:

{

"subversion": "/Satoshi:0.20.1/",
"protocolversion": 70015,
"localservices": "0000000000000409",

},
{
"address": "my.onion.adress2.onion",
"port": 8333,
"score": 4
}
],
"warnings": ""
}

and one more that I think it can prove I'm connected to the "internet/other nodes/peers". bitcoin-cli getpeerinfo
