Hi, I tried to recreate a security group and still have the same error. Attached is the screen shot I have for the security group. I was able to launch the galaxy instance last year without any problem. Not sure what had changed, Can you tell if there is anything wrong in the security group configuration?

Did you click Apply Rule Changes when you finished adding rules? Other than that, I'm not sure what the problem is, but I have not used cloudman before. I followed the instructions and it works for me. Dan

Thanks, Julia

Hi, This is Julia from Memorial SLoan-Kettering Cancer Center. I've been using the galaxy Cloudman instance last year and it worked fine. But today when I tried to launch instance galaxy-cloudman-2011-03-22(ami-da58aab3). After the instance was running, it gave me "tcp_error: A communication error occurred: "Connection refused". Any ideas?

Sounds like maybe a security group problem. Did you set up your security group as described here: http://wiki.g2.bx.psu.edu/Admin/Cloud

Search for "Add Inbound Rules". Dan

Thanks a lot, Julia
