504 Gateway Time-out

Hallo ich habe das problem das ich wenn ich versuche auf die webseite zu kommen nur nach sehr langer zeit den Fehler 504 Gateway Time-out erhalte.
Bei let´s debug (Let's Debug)habe ich den Fehler :


No valid A or AAAA records could be ultimately resolved for themccrafter.net. This means that Let's Encrypt would not be able to connect to your domain to perform HTTP validation, since it would not know where to connect to.

No A or AAAA records found.
My domain is: ‘Themccrafter.net

I ran this command:N/A

It produced this output:N/A

My web server is (include version): Nginx Proxy Manager v2.9.19 (latest)

The operating system my web server runs on is (include version):
Ubuntu 22.10

My hosting provider, if applicable, is: N/A

I can login to a root shell on my machine (yes or no, or I don't know): yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Nginx Proxy Manager

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.31.0

I don't see "504 Gateway Time-out".

I do see:

Which can be confirmed with:
nslookup themccrafter.net

I do see an IP for the "www":

nslookup www.themccrafter.net
Name:    www.themccrafter.net

Danke für deine Antwort

The site http://www.themccrafter.net/ is accesible:

curl -Ii www.themccrafter.net
HTTP/1.1 301 Moved Permanently
Server: openresty
Date: Fri, 17 Feb 2023 11:45:37 GMT
Content-Type: text/html
Content-Length: 166
Connection: keep-alive
Location: https://www.themccrafter.net/
Strict-Transport-Security: max-age=63072000; preload

The redirected HTTPS site is having trouble [eventually returning 504 error].

But when I access port 443 using HTTP request, it answers:

curl -Ii http://www.themccrafter.net:443/
HTTP/1.1 400 Bad Request
Server: openresty
Date: Fri, 17 Feb 2023 11:47:34 GMT
Content-Type: text/html
Content-Length: 252
Connection: close
Strict-Transport-Security: max-age=63072000; preload

That looks like it can't speak securely.
