app was not started ! ./discourse-doctor may help diagnose the problem. ./discourse-setup: line 260: *0: syntax error: operand expected (error token is "*0") Hostname for your Discourse? [discourse.example.com]: .com Checking your domain name . . . WARNING: Port 443 of computer does not appear to be accessible using hostname: .com. WARNING: Connection to http://.com (port 80) also fails. This suggests that .com resolves to some IP address that does not reach this machine where you are installing discourse. The first thing to do is confirm that .com resolves to the IP address of this server. You usually do this at the same place you purchased the domain. If you are sure that the IP address resolves correctly, it could be a firewall issue. A web search for "open ports YOUR CLOUD SERVICE" might help. This tool is designed only for the most standard installations. If you cannot resolve the issue above, you will need to edit containers/app.yml yourself and then type ./launcher rebuild app I have couple questions : * I have .com and there is site already running . Now I want to run discourse as .com/discourse . The app is running in front of load balancer . But do i need to anything on discourse side * what port discourse is running ? * When i do curl I can reach to the site but why discourse setup is erroring out * is it ok ignore mail setup
