i hit this when ~/.localslackirc did not end with \n (created with xclip -o > .localslackirc)

file .localslackirc 
.localslackirc: ASCII text, with no line terminators

editing the file resolved RTM connection attempt failed

Now

file .localslackirc 
.localslackirc: ASCII text

client sees

08:33 -- irc: connecting to server localhost/9007... 08:33 -- irc: connected to localhost/9007 (127.0.0.1) 08:33 -- Welcome to localslackirc

server says

Connecting to slack... Fetching history... No last known timestamp. Unable to fetch history Connected to slack
