Olá,  
Esta é provavelmente uma pergunta básica, mas: estou tentando instalar o Discourse no meu servidor Ubuntu, mas sempre recebo este erro:

 ![2022-09-07 23_18_47-root@v2202001112289107119_ _var_discourse](https://global.discourse-cdn.com/meta/original/4X/1/7/e/17e61615fc8c7ba8d3d94e67312c48cf0ba1c1d9.png)

Minhas configurações de DNS parecem corretas:

 ![2022-09-07 23_21_59-DNS _ yayeet.org _ Ytimo.komentarhotlinne@gmail.com's Account _ Cloudflare – Ope](https://global.discourse-cdn.com/meta/original/4X/c/2/3/c23ab43ca2e33d1a90242cb2c22d0a732e825bb9.png)

Como posso corrigir isso?  
Obrigado desde já!
