Does your machine have a public IP address? And did you open the port 17012 in the firewall? If you do open it, you have much better chances of finding a peer.
Also you need to make sure your wallet indeed finds and opens the "quatloo.conf" file. Change some settings in the file, restart the wallet and look into the logs to see if they are applied.
My IP is determined through Internet services, so I think I have an external IP))) I don't have a firewall. The version of my wallet is 0.1.2.1. Maybe it is outdated?
The logs constantly repeat 2 lines:
2018-12-15 18:59:52 connection timeout
2018-12-15 18:59:53 trying connection 72.78.100.7:17012 lastseen=106.6hrs
Wallet settings are as follows:
server = 1
daemon = 1
listen = 1
...
Obviously you'll need running tor for that.
