I have a MapD server running in an Amazon EC2 Redhat 7.3 machine in a g2.2xlarge GPU instance. From the screen shot below, it can be seen that I am able to insert data and perform query through mapdql.
However, I have been unable to connect to immerse through my web browser. I attach another image with my port inbound rules for the Redhat instance. When I try to connect through it is giving me ERR_CONNECTION_RESET in chrome. I believe I have successfully configured the dynamic port forwarding because I have been using the MapD community edition Amazon AMI before. The blurred portion in the image below is my laptop ip.
