I am having issues. I had this working for about a week and yesterday it stopped working. I haven't changed any settings it just won't work anymore. I keep getting the msg that say to lower the (-h) value I had been running it set to 50 in the first place. The cards are stock AMD R290s, no overclocking or anything like that. edit: I made some changes like running in ssl on port 9000 and get the same issue no matter what I change the (-h) value to.
