I was trying to get my bitcoin node to be able to receive ipv4 peers for couple of days, but could not see any incoming peers even tho my port 8333 was open and reachable and to my best knowledge bitcoin.conf is correct. Today I have spin up another node and used addnode=mainnodeip to see whether I can connect to my main node. Connection out went fine, data is being received, but still in bitcoin-cli -netinfo of my main node I don't see this connection.Is this a bug? I can see the outbound connection on my testing node, but not inbound in my main node.
Thank you for any tips or explanation.
