`./discourse-setup`을 실행할 때마다 이 오류가 계속 발생합니다. 해결 방법이 있을까요? (VM IP를 가리키는 DNS A 레코드를 추가했습니다.) ``` Checking your domain name . . . WARNING: Port 443 of computer does not appear to be accessible using hostname: forum.roblox-devs.com. SUCCESS: A connection to port 80 succeeds! This suggests that your DNS settings are correct, but something is keeping traffic to port 443 from getting to your server. Check your networking configuration to see that connections to port 443 are allowed. The first thing to do is confirm that forum.roblox-devs.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 ``` ![image](https://global.discourse-cdn.com/meta/original/3X/d/2/d2160a9219b93f2754f8cf7a1819bb2641f50e6c.png) ---

안녕하세요. 👋 스크린샷에서 IP 주소를 마스킹한 이유는 무엇인가요? _공개 DNS 기록_과 일치해야 하는지 확인이 어렵습니다: ```plaintext $ dig forum.roblox-devs.com ; <<>> DiG 9.11.21-RedHat-9.11.21-1.fc32 <<>> forum.roblox-devs.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 12504 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 9 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;forum.roblox-devs.com.

늦게 답변드려 죄송합니다. `./discourse-setup`를 실행할 때마다 다음 오류가 표시됩니다: `WARNING: Port 443 of computer does not appear to be accessible using hostname: forum.roblox-devs.com.` `WARNING: Connection to http://forum.roblox-devs.com (port 80) also fails.` 해결 방법이 있을까요? ---

Apache가 포트(ports)를 점유하고 있습니다. Apache를 사용하지 않으신다면 비활성화하거나 제거하는 것이 좋습니다. ---
