I have installed JIRA 7.0.9 on Ubuntu server 14.04.3 with a remote MySQL database server. At one point I was able to access the app server via http://IP:8080, but cannot now after trying to resolve some db and app server connectivity. I have tried changing the shutdown and operating port for the app, and shutting down the Ubuntu FW (sudo ufw disable). The VM is an Azure VM so ping is not enabled. I am unable to telnet to the operating port which leads me to believe its a FW or networking issue. Azure endpoints are open for the TCP protocol from my network to the VM. I tested with config.sh and there is connectivity between the db and application server.
