OK, I finally have a build of the Windows pool miner for people who have connection problems to try. You can download it from here:
https://nrs.blockquarry.com/miners/windows_coyote_miner.0.3.3.zipThe included batch file shows the new syntax that lets you specify port numbers. The default was 4444 but I have added 4020 and 10013 as well. I have tested this on a Windows 7 and 2008 R2 system I have access to. Not a Windows user myself so it has had very limited testing.
Can someone who is getting blocked give this a try? Hopefully whatever is blocking the mining traffic for some of you is doing this based on port numbers. If not then it may require a whole different protocol than what the coyote miner uses before you can connect.
