These ports are closed now, because nscrypt is more profitable. Check main page on NiceHash - algorithm marked with green is most profitable.
If you want to mine X11 or X13, use 3336 and 3337 ports.
Thanks. I understand now how it is working. One enhancement that would be good is if you could still do the multi-algo switching to the most profitable algorithm of just the algorithms you want to mine. A lot of people are like me where scrypt mining is just to hot this time of year.
