Only 10 connections on my raspberry pi full node

Question

I'd like to know why I only get 10 connections on my full node? Is there something missing in the conf file?

$bitcoin-cli -netinfo

Bitcoin Core v0.21.0.0-7d8a10a6f - 70016/Satoshi:0.21.0/

	ipv4	ipv6	onion	total	block-relay
in	0	0	0	0	0
out	7	0	3	10	2
total	7	0	3	10	2

Local addresses
*myadress*.onion     port   8333    score      4

my bitcoin.conf file

#Tor stuff
proxy=127.0.0.1:9050 #outgoing
listen=1 #enable download of new data
bind=127.0.0.1
deamon=1 #to run binary in background s.t. console is free
server=1 #to access deamon API
rest=1 #deamon offers web service so other tools like curl can access it
rpcuser=myuser
rpccallowip=127.0.0.1
rpcbind=127.0.0.1
maxconnections =50

Let me know if you need more info, thx!

Answer 1

bind=127.0.0.1

Binding the p2p port to localhost means that it can not accept incoming connections from anywhere other than software on your own machine.

listen=1 #enable download of new data

This allows incoming connections to whatever is configured by bind, it doesn't have anything to do with downloading data yourself.

You can put the public address of your node in https://bitnodes.io and add monitoring. Mine gets more connections after that. Also manually add the content of known nodes, you can found here:

And here by clicking on "node list":
