Guys, you all are using beta software with beta ports. If you expect stability and no disconnects, you should use something stable, even if it's less hash. For me first working V5 version was from 30.06, all other versions did not even start and if it started mining, exactly after 60 seconds sgminers quit.
You can get new miner from
nicehash, version 2014-07-08. For me there is no difference in last 2 versions, both work flawless. There was only 1 thing I still do not understand. For some reason I needed to restart my pc when I tried last version. I was mining with 2014-06-30 version, quit with "Q", started version 2014-06-30. Miner did not start and it did not give me any popup or message. I restarted and everything started to work.
As everything is beta, error could be anywhere. I was solo mining, that's why I can say that the issue is probably on sgminer side, but you never know, there could be also some error in server configuration.
If it happens to someone in the night, just switch the miner for the night until the issue is resolved.
BTW: Who gave version 5 to the new miner? It's actually in version 4.2.2. It should be something with 5.x, it's confusing using 4.2.2 and calling it v5.
