Hi, I have Discourse configured on port 90 and 453. The container also runs on these ports, but although these are also open, Discourse is still not reachable!

Letsencrypt needs port 80 to verify the hostname for ssl. Failed ssl verification results in no certificate being issued and that’s probably what is causing your discourse to not show up. Do the right thing, use port 80 & 443.

Another version of the answer you got already is that nonstandard ports are not supported. I recommend that you get another vm, but there are topics like How to set up Discourse on a server with existing Apache sites

端口 - 无法访问

支持安装

另一种你已经得到的答案是，不支持非标准端口。我建议你再获取一个虚拟机，但也有一些话题，比如如何在带有现有 Apache 网站的服务器上设置 Discourse。
