Been trying to get my antminer a3 working on mph for siacoin but no luck. I've tried port 17022 and 20550 both connect only for a few seconds then disconnect. I don't have this problem on other pools and also don't have this problem connecting a l3+ to mph. A bunch of people seem to have this problem on reddit. If anyone knows a solution let me know. I also tried setting the difficulty manually in the password field but maybe it's the wrong setting didn't seem to change anything though.
