Hi, I followed this instruction guide, but the “site can’t be reached” error occurs after installation. Does anyone have an idea how to fix this?

In which case that’s almost certainly the problem. You can only reissue 5 times in a week, so if you’re set on that DNS name you won’t be able to reinstall until a week has passed. Renewals are treated specially: they don’t count against your Certificates per Registered Domain limit, but they are subject to a Duplicate Certificate limit of 5 per week Once you have everything installed just backup your instance. That way if you want to make changes you can just restore a fresh site.

A quick stupid question… how to check this?

Does this error indicate something? root@vultr:/var/discourse# curl http://149.28.40.194/ curl: (7) Failed to connect to 149.28.40.194 port 80: Connection refused

connection refused means something is preventing connections to your server. Which host are you using?

What do you mean by “which host”? Ip address?

I mean the VPS provider? is it vultr? have you configured discourse to use a FQDN? Additionally, can you confirm what OS you’ve configured on your VPS? if it is ubuntu 18.04 or higher, can you post the output of sudo ufw status ?

yes, i’m using ubuntu 18.04 root@JYC_Test:/var/discourse# sudo ufw status Status: inactive

Sure, but where is the server hosted? Have you confirmed that the “A” record for your DNS address is resolving to the droplet IP? How was this installed? The standard installation checks these things before the server is installed.

A record is correct. Because I literally did the same process a few days ago on the same server, and it worked perfectly fine. I reset the server to install it again today, this error occurs.

You mean the physical location? New Jersey

How many times did you try setting the site up? If that’s a Let’s Encrypt certificate then they do have an issuance limit, and a cooldown period.
