[galaxy-user] Galaxy in AWS AMI

Hi, Can somebody please help me? I'm trying for hours to connect to Galaxy on Amazon EC2. I did everything according the instructions, but did not succeed. The "Access Galaxy" button in the instance remains grey out. I copied the screen print and the log to the attached file. Can anyone help me please? and another questions: I want to use it to analyze MiSeq results (to align to the human genome). 100 Gb EBS and a large machine are enough? too much? Many thanks, Lilach.
