having issues connecting. Tried the built in url on guiminer, and I also tried stratum2.bitcoin.cz:3333 and stratum3.bitcoin.cz:3333 to no avail. Connection is just not happening, something about IO errors
I had the same issue today with one of my machines running guiminer. I had to flush my dns and it started working again with the standard slush setting in guiminer.
in case you don't know:
ipconfig /flushdns
In windows vista or 7 you want to open the cmd as administrator.
EDIT: and just to be clear, I'm not using Other for my server, I'm actually using the slush server option.
