Hi, I’m trying to install Discourse on a cloud server from Hetzner but when running ./discourse-setup I get the message that ports are blocked ( domain.de is obviously not the real domain): WARNING: Port 443 of computer does not appear to be accessible using hostname: discourse.domain.de. WARNING:…

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: [图片] Hetzner experiences There was one new issue that I discovered – the discourse-setup failed on error message which suggested that port 443 would b…

Have you looked up the DNS using an external service? Ie. One that is not routing through your cloud host provider? [图片] DNS Lookup Tool – Check DNS Records and Nameservers Explore fast and reliable DNS lookup tools, domain information, and essential network utilities all in one place …

I have not done that before, thanks for the tip. It shows the correct IPv4 address.

You are getting that message because those ports are being blocked by Hetzner.

Somehow off topic but do you know why Hetzner would block such important and yet trivial ports?

Okay, thank you. I will contact the support of Hetzner.

To avoid abuse. https://docs.hetzner.com/cloud/servers/faq/ Unfortunately, email spammers and scammers like to use cloud hosting providers. And we at Hetzner naturally want to prevent this. That’s why we block ports 25 and 465 by default on all cloud servers. This is a very common practice in the …

That is common solution and one reason why self hosted email server is close to impossíble. But OP had issues with ports 80 and 443. Or did I miss something?

You are right. I mixed up two different issues. Apologies for the confusion.

I’m still confused, but at Digital Ocean firewall must be set up. Clean install doesn’t have any ports open (except for SSH but that is dfferent thing). I don’t know how Hetzner works. And if VPS is behind closed ports, it doesn’t matter what we have on app.yml. Or am I again missing something?

Manual configuration of app.yml is the solution to the problem for me as well. Thanks! I also found this thread, but I guess I didn’t read it carefully enough… :see_no_evil:

您是否已使用外部服务查找了 DNS？

例如，不是通过您的云主机提供商路由的服务？
