I was just trying to use the auto-switching but it doesn't seem to work for me. When I set pool ports to 33xx, everything works perfectly, I can manually switch pools and all pools work, however when I switch it over to 43xx and start the sgminer, it says that all pools are dead after a while. Any suggestions?
Perfectly normal; in order to 'switch' only one algorithm can be 'selected' at a time. All of NH ports that start with 43xx are multi-algo ports, which will shut, so when 1 is selected, the other 4 algos go dead. If you have no failovers, it is possible you may get no work served if there are not enough orders up for that algo.
I understand that, but there surely IS some work at least for scrypt, since when I go manual, it works. So it's unlikely that there's no work for any algo...
