I have recently opted to do a self-host of discourse on aws.
I followed all the instructions on the github page. I receive a connection timeout error. The installation works fine. The DNS A record is set up correctly and my host has confirmed that it works.
On aws my instance is a Ubuntu Server 18.04 LTS (HVM), SSD Volume Type with 2GB and 1vCPU.
Every time I access the page I receive a connection timeout error.
