< p > If you experience repeated connection issues make sure to check the bitcoin-s.log file. If the logs show that Bitcoin-s is able to connect through the tor proxy (< code > connected to neutrino.suredbits.com/:8333 via SOCKS5 proxy /127.0.0.1:9050< / code > ) but is not able to connect through the tor controller (< code > TorController refused to connect< / code > or similar) you may need to make additional changes to your torrc file. Find the location of your tor control_auth_cookie file and add the pathname for this file to your torrc file as show below.
