All "socket connection failed: connection refused" means is that bmminer isnt running. The webpage tries to pull the version numbers from the API of bmminer so whenever the miner isnt active, it will get a connection refused on the API port. People often confuse this as an error message when really its not.
It sounds to me like you might have some IP address conflicts on your local network. Do you run DHCP or do you give your miners static IPs?

Im not sure. The GPU miners have never changed there IP's. BUT the Antminers have been changing every time I upload the new firmware on them or rebot them.
