Cant obtain certificate with pterodactyl installer

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: bash <(curl -s

It produced this output: Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Type: connection
Detail: Fetching Timeout during connect (likely firewall problem)

My web server is (include version): nginx 1.18.0

The operating system my web server runs on is (include version): Ubuntu 22.04

My hosting provider, if applicable, is: Oracle Cloud

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):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 1.21.0

Hi @andrei1010gaming, and welcome to the LE community forum :slight_smile:

The error seems quite clear.
Can you reach that site from the Internet via HTTP?


what do you mean?

LE can't reach your site:

I can't reach it either:

curl -Ii
curl: (56) Recv failure: Connection reset by peer

weird. when i use the default DNS provided by the domain service (STRATO in my case) it just works fine.

with that I mean it shows up in my browser

DNS works for me too:


DNS is not the problem.
HTTP access to that IP/name from the Internet is the problem:

curl -Ii
curl: (56) Recv failure: Connection reset by peer

curl -Ii
curl: (56) Recv failure: Connection reset by peer

hun, ok

Are you connected locally to that server?
Maybe via WiFi?
You need to test access from the Internet.


i see this in STRATO:

Forward Target Address: Inactive

i am in SSH with that server im trying to install pterodactyl on

Not from within the same server nor local network.
The pterodactyl installation is trying to obtain an LE SSL certificate via HTTP authentication.
That means HTTP://your-site must work before it can get that cert.


i removed the dns and it seems to work

The installer is exposed. Is that an issue here?


what do you mean? this is a public installer everyone can use

Not the downloadable installation file.
Your server may be exposing the pterodactyl configuration page.


you need a password to access it

but the webpage doesnt show up at all
