Im having a problem connecting to my btc username with my x11, x15 and scrypt miners.  my sgminer for x11 and x15, on both instances, says, waiting for pools and after a while, "no servers could be found to get work from".  here is my config for the x11 miner:


{
"pools" : [
   {
      "url" : "stratum+tcp://mine.zpool.ca:3533",
      "user" : "1N4euqDASdAG5z1QWfv3BtfgNp3z3u6Rfo",
      "pass" : "x"
   }
]
,

and my conf for the x15 miner:

   {
