With '0 (in)' you may have your port blocked. That's okay, it'll still work, but you can get more connections if you open it.
I get this in aeond: 2020-05-10 17:40:14.960 [P2P8] WARN global src/p2p/net_node.inl:1339 [1;31mNo incoming connections - check firewalls/routers allow port 11180[0m
But it looks like the port 11180 is open. I checked on canyouseeme.org. I also have UPnP enabled and aeon is listed under the UPnP service list.
After 24 hours uptime, now showing 8(out)+0(in). I am fully synced, though, so it is working, like you said.
Any ideas for me to try? Just want to help the network.
Also, monerod is working fine with many connections in and out.
