Unable to change domain name

[bjrno]

Hi all,

I followed the tutorial to install discourse on a digital ocean droplet which works great.

It was installed using discourse.mydomain.com but now I want to move it to mydomain.com without the subdomain.
Obviously I set the dns records correctly and checked if they were actually changed by pinging the domain from my computer and also from the cli of the droplet. All fine.
Added the domain to the droplet.
I edited the app.yml and changed the host name. Did ./launcher rebuild app (a hundred times by now)

After this, my discourse site is unreachable by both old and new url.
If I edit the app.yml and rebuild again with the original subdomain it works again.

I have been trying to get this to work for the past three hours now and I must be missing something trivial. Can anyone tell me what I am missing?

Thanks
Björn

Did you read the documentation on domain changes?

Change the domain name or rename your Discourse

This guide is for self-hosted Discourse instances that were installed using our installation guide on GitHub. If you are hosted by Discourse, please see Configure your domain name for hosted Discourse for specific instructions. You may eventually want to change the domain name of your Discourse instance, from say =BEFORE= → =AFTER= Let’s get started. Set the TTL for your DNS low, and in advance You need to let everyone know that the domain is about to change, so change the TTL f…

Yeah I did exactly that. Somehow the droplet / discourse installation doesn’t respond to the right domain.

How many times did you try to change the domain?

Are you using let’s encrypt?

Are you using any kind of proxy server, or Cloudflare?

[bjrno]

By now I’ve changed my domain multiple times over the course of a couple of hours (although it obviously also wasn’t working when I changed the domain the first time).
I am using Let’s Encrypt indeed. I followed the installer and it was enabled by default. I didn’t enter the let’s encrpyt mail address since my understanding is that it only for notifications.
No proxy server or cloudflare.

FPV-Racing.nl

The DNS of fpv-racing.nl is currently restored to the previous IP.

Changing DNS records can take anything from 4 to 24 hours to update.

It’s not an immediate thing. There are ways to shorten the wait period, but that’s up to the domain Provider

[bjrno]

DNS wasn’t the issue. The domains all pointed to the right IP. Checked with dig and ping from both my Mac and the digitalocean droplet cli.

[bjrno]

Checked the logs after a rebuild and it seems there is an issue with Let’s Encrypt. Does anyone know what can be causing the errors? There is also a let’s encrypt certificate on the old server.

When manually requesting the certificate (found the procedure on this page) I get the same error for fpv-racing.nl. For discourse.fpv-racing.nl I get ‘success’.

By now I seem to have hit the rate limit for this hour (too many failed authorizations recently).

I think this is the culprit… I haven’t removed the old ipv6. Now wait for the rate limit

[bjrno]

It was indeed the issue. Never paid attention to the ipv6 settings… Thanks for your input guys
