Hi, I just tried to install Discourse. I have actually also successfully completed this via a DigitalOcean Droplet. But now when I call the domain I get a 404 error message.
What confuses me a bit is the fact that my domain host takes a screenshot of my website. And on this one you can see the finished installation, as shown on the attached screenshot.
I used the one-click installer. I don’t really fixed it.
I have now noticed that I can also see the installation with my smartphone via mobile data instead of WLAN. But I do not receive the email for the account creation. And on the computer with wifi I still get the 404 error.
Sounds like DNS propagation issues. According to DNS Checker - DNS Check Propagation Tool it looks like it should be resolved. You might try an incognito window on your desktop or try another browser.
I think you just wait. Or it could be that whoever is providing your DNS service to your computer has cached an old value. You might try https://1.1.1.1/
