if someone could help thank you
You're using Cloudflare CDN. Please make sure you have a working website first.
If you're using Cloudflare, you might want to look into Cloudflares Origin CA certificates instead of using Let's Encrypt certificates on your origin server.

Cloudflare can sometimes interfer with the challenge for some reason. I'm not really familiar with Cloudflare and the many options one can enable at Cloudflare, so maybe another volunteer can help you with that.
Alternatively you could still look into the origin certificates from Cloudflare, see the link I posted earlier.
You do have AAAA records. They are part of the Cloudflare "proxy" setup you did. These are their current values:
zypher.site. 0 IN AAAA 2606:4700:3036::ac43:875b
zypher.site. 0 IN AAAA 2606:4700:3035::6815:1a27
I believe Cloudflare CDN uses IPv4 to your Origin Server unless it is IPv6 only. That is something to discuss on the Cloudflare community or from its docs.
It produced this output:
rena@renaserver:/etc/nginx/sites-available$ sudo service nginx start
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.
My web server is (include version):
nginx
The operating system my web server runs on is (include version):
ubuntu 24.04 lts
My hosting provider, if applicable, is:
nginx? cloudflare?
I can login to a root shell on my machine (yes or no, or I don't know):
i dont know
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
certbot 2.11.0
The problem im having is that before i had installed the certbot everything was working fine i could access the website outside of my home wifi but when i installed certbot nginx wont turn on
I moved your new post/thread onto this one. This is a continuing problem and it is helpful for us to see the history in one place.
What do these commands show?
As an alternative to Certbot on your Origin server, have you looked at the link Osiris provided about using a Cloudflare Origin CA cert? That may be far easier for you than the path you are on.
Even that requires a working nginx server though. You need to show the error messages from the above for us to help though.
LE prefers to use the AAAA record when available - as shown in the error message:
Also shown is the "523" message from Cloudflare - which I think means that they can't connect to your site.
You need a working website in order to get an LE cert via HTTP(S).
That said, you may not even need an LE cert - Since you can get a cert directly from Cloudflare.
