hi, new here 
seems like a good place to request help for my problem. I mine using a few nvidia GPUs to zergpool for auto-exchanging and it used to work just fine. I sometimes would switch mining apps based on profitability. a few weeks ago I started getting errors of type "No connection could be made because the target machine actively refused it". It would happen with every pc with a gpu (all on the same local network) and every app, except for gminer which always works! if I try to mine the same algo, using same settings, on the same gpu, but with a different miner - no good. Now I know that it might not be the biggest problem since I can actually mine, however sometimes I'd like to mine something not supported by gminer or just a more efficient miner. Adding to the mystery is that there are times when I do manage to get a connection with a different miner, then it works for something between a few minutes to maybe an hour, and after that the error again. Usually it takes a few hours to "reset" itself. The problem has to be at my end, but can't figure out what to look for since gminer always connects and I don't recall any changes being made to my connection/router options. Any ideas?
