I get the date/time stamp and message "Started cgminer 4.11.1" then it freezes for approx 30 secs before saying its either the server, URL, check details or set up workers. It then cycles between Pool 0 difficulty changed to 10000 and Pool 0 message: Failed auth
Are you entering your pool information with user name?
Post your command line that you are starting CGMiner with. You mentioned a .sh file too so post the contents of that as well.
