I have setup membase server on AWS EC2 instance. I security groups I have opened all ports for client's IP address. When I access it through telnet (using port 11211) I get following error
membase SERVER_ERROR proxy write to downstream
But when I change settings in security group to allow access to everyone(0.0.0.0/0) rather than specific IP, it works fine.
In first case client have access to membase server, thats why it connects using telnet, but gives error for queries.
I can not leave all ports open for everyone. Please help to solve this.
