404 error issuance to CloudPanel domain

infiev · October 21, 2020, 8:06pm

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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: xn--silkebkken-hagen-zob.no

I ran this command: "Create and Install" button in CloudPanel

It produced this output: www.xn--silkebkken-hagen-zob.no: Domain could not be validated, error message: error type: urn:ietf:params:acme:error:unauthorized, error detail: Invalid response from http://www.silkebækken-hagen.no/.well-known/acme-challenge/lkpU3tMrmXDbk0G0XSRI7dDkB0j8lGgchY4u_rCfQC4 [2001:4da8:c:1b::]: "\n\n404 Not Found\n\n

Not Found

\n<p"

My web server is (include version): NGINX 1.18.0

The operating system my web server runs on is (include version): Debian 10.6

My hosting provider, if applicable, is: Digital Ocean

I can login to a root shell on my machine (yes or no, or I don't know): Yes (but shouldn't be necessary on CloudPanel).

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): CloudPanel 1.0.3

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

You have an IPv6 address configured for your domain, but it's answering differently than your IPv4 address. Perhaps the AAAA DNS record points to a whole different server or the IPv6 address is correct, but your server is misconfigured.

infiev · October 21, 2020, 9:45pm

Thank you very much for your reply!

I have now fixed the AAAA record and it has gotten me one step further. Now, unfortunately, I get another error saying "www.xn--silkebkken-hagen-zob.no: Domain could not be validated, error message: error type: urn:ietf:params:acme:error:connection, error detail: Fetching https://silkebækken-hagen.no/.well-known/acme-challenge/qA3Xsj_iiewXX_p0hspzlyL5_y4Z2MH7kUM5IBiQYpI: Timeout during connect (likely firewall problem)"

I have opened up all ports for both IPv4 and IPv6. Can you see what the issue is now? Could there still be something wrong with the DNS?

rg305 · October 21, 2020, 10:08pm

DNS does not seem to be a problem now.

The HTTP challenge requests are being redirected to HTTPS.
So: http://silkebækken-hagen.no/.well-known/acme-challenge/*
Goes to: https://xn--silkebkken-hagen-zob.no/.well-known/acme-challenge/*
But that returns 404 not found.

Let's place a test file in the expected challenge folder.
First: Find the root folder for the vhost.
Second: Create the folders (if needed)
mkdir /whatever-root-you-have/.well-known/
mkdir /whatever-root-you-have/.well-known/acme-challenge/
Third: Place the test file in the challenge folder:

echo "test file" > /whatever-root-you-have/.well-known/acme-challenge/test-file-1234

[do not create a test file with any extension - this will better approximate an actual challenge file]
[do not add .txt nor .html nor anything to the end of the file name]

infiev · October 22, 2020, 6:06am

The folders .well-known/acme-challenge/ were already there, and I have added a file called test-file-1234 that reads: echo "test file"

I'll also share the Vhost code here in case that helps. It is the standard CodeIgniter template in CloudPanel:

  listen 80;
  listen [::]:80;

    break;

Doing HTTP and HTTPS in the same block is unnecessarily over complicating an otherwise simple situation.

I would try them separately as:

server {
  listen 80;
  listen [::]:80;
  server_name www.xn--silkebkken-hagen-zob.no;
  return 301 https://xn--silkebkken-hagen-zob.no$request_uri;
}

server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  {{ssl_certificate_key}}
  {{ssl_certificate}}
  server_name xn--silkebkken-hagen-zob.no www1.xn--silkebkken-hagen-zob.no;
  {{root}}
...

Then this can be removed:

And this can be modified as case-insensitive as:

Thanks for the suggestions! I have now updated the Vhost with your changes. Unfortunately, it doesn't appear to fix the problem. I am still getting the same error message:

Is port 443 open to your server?

[&2* readers: Get involved; Be heard. It starts with: if you read something you like, then like it ]

infiev · October 22, 2020, 7:32am

Yes, port 443 is open. I have temporarily opened all ports in the firewall while debugging. I just double checked 443 in a port checker as well.

The document root folder listed in CloudPanel is /home/cloudpanel/htdocs/xn--silkebkken-hagen-zob.no/public

rg305 · October 22, 2020, 7:35am

Not sure why HTTPS is failing:

But that connection implies that it read the HTTP redirection.
So, we could switch to HTTP instead with:
[move, or copy, this to the HTTP block]

AND ADD:
{{root}}

infiev · October 22, 2020, 7:39am

I'm not 100% sure I understood you correctly, but this is what I have now:

server {
  listen 80;
  listen [::]:80;
  server_name www.xn--silkebkken-hagen-zob.no;
  return 301 http://xn--silkebkken-hagen-zob.no$request_uri;
  {{root}}
  
  location ~* /.well-known {
    auth_basic off;
    allow all;
  }
}

  {{ssl_certificate_key}}

  server_name xn--silkebkken-hagen-zob.no www1.xn--silkebkken-hagen-zob.no;
  {{root}}

  {{nginx_access_log}}
  {{nginx_error_log}}

  if ($bad_bot = 1) {
    return 403;
  }

  location ~* /.well-known {
    auth_basic off;
    allow all;
  }

  {{basic_auth}}

  try_files $uri $uri/ /index.php?$args;
  index index.php index.html;

  location ~ \.php$ {
    include fastcgi_params;
    fastcgi_intercept_errors on;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    try_files $uri =404;
    fastcgi_read_timeout 3600;
    fastcgi_send_timeout 3600;
    fastcgi_param HTTPS $fastcgi_https;
    {{php_fpm_listener}}
    {{php_settings}}
  }

  location ~* ^.+\.(css|js|jpg|jpeg|gif|png|ico|gz|svg|svgz|ttf|otf|woff|eot|mp4|ogg|ogv|webm|webp|zip|swf)$ {
    add_header Access-Control-Allow-Origin "*";
    expires max;
    access_log off;
  }

  if (-f $request_filename) {
    break;
  }
}

And it returns this error:

rg305 · October 22, 2020, 7:43am

Yes that is what I expected
Although, on second thought, the server_name lines should be the same:

And there is a "1" in the second line that might have been added by accident

So they both fail ! ? ! ? ! ?
hmm...
Do you have an IPS, or firewall, or Geo-Location blocking device in line?

rg305 · October 22, 2020, 7:48am

On third thought...
Maybe this is confusing:

And could be better stated this way:

  #skip challenge requests and
  location ^/(?!\.well-known) {
    #send all other requests to HTTPS
    return 301 https://$host$request_uri;
  }#location
  auth_basic off;
  allow all;

[move {{root}} above that section]

It works! Thank you so much for the help!
