端口被阻止（Hetzner 云服务器）

[JammyDodger]

I’ve had a forum search to see if anyone else had encountered a similar issue and found this, though unfortunately not a ‘true solution’ as such:

@ljpp

There was one new issue that I discovered – the discourse-setup failed on error message which suggested that port 443 would be unreachable . This was on a clean default configuration, with no firewall rules defined. I did not find an obvious reason why this occurs, going though the relevant topics here, disabled CloudFlare caching, but the issue persisted.

Then I just configured the app.yml manually and it worked perfectely, with Let’s Encrypt, https:// and everything.

Could configuring the app.yml manually be an option for you?
