Failed authorization procedure.The client lacks sufficient authorization

Hey, so I'm trying to create SSL certificate and I'm facing problems as mentioned below. please help :slight_smile:

My domain is: http://login.theconcov.com/
I ran this command: sudo certbot --nginx -n --redirect -d login.theconcov.com

It produced this output:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator nginx, Installer nginx
Obtaining a new certificate
Performing the following challenges:
http-01 challenge for login.theconcov.com

Failed authorization procedure. login.theconcov.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from Loading... [3.213.80.151]: "<!doctype html>\n\n \n Loading...<meta data-n-head="1" charset="utf-8"><meta data-n-head="1" name="v"

IMPORTANT NOTES:

  • The following errors were reported by the server:

    Domain: login.theconcov.com
    Type: unauthorized
    Detail: Invalid response from
    Loading...
    [3.213.80.151]: "<!doctype html>\n\n \n

    Loading...<meta data-n-head=\"1\" name=\"v"

    To fix these errors, please make sure that your domain name was
    entered correctly and the DNS A/AAAA record(s) for that domain
    contain(s) the right IP address.

My web server is (include version): nginx/1.14.0

The operating system my web server runs on is (include version): ubuntu 20.04.2 LTS

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): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):certbot 0.31.0

Hi @shreyanshnanavati

looks like you have found a solution :+1:

Checking your domain with my browser there is a new certificate, created today. Looks good!

Hi @JuergenAuer

Yes, I did find a way to solve it, but initially, I used to generate the certificate using the following command: certbot --nginx -d domain.com which worked till a few days back, but now it throws the error mentioned above.

I got it to work using the following steps

  1. sudo certbot certonly --webroot --webroot-path=PATH -d domain.com which generated the certs.
  2. and then when I ran certbot --nginx -d domain.com and selected the reinstall option and restarted my Nginx and then it worked.

So can you please help me out, I want it to work with just certbot --nginx -d domain.com.

Hi @shreyanshnanavati,

This suggests that Certbot is having trouble parsing and editing your nginx configuration properly. (That's not at all impossible—it's less common than it used to be, but it can still happen.)

Do you just have one copy of nginx on this machine, with port 80 directly exposed to the Internet, with nginx listening on port 80, and no other reverse proxy or anything? Are you running Certbot directly on the same server with that copy of nginx, and not in a different container or anything?

Is there anything unusual or unusually complex about your nginx setup?

If that doesn't work: What says

nginx -T

Hey sorry for being late to reply. Here's my content, also to give you a brief idea, what we have implemented is to replicate a multi-tenant architecture for our app, that lets our customer run our app on the custom domain. So to achieve that our PHP script creates a new Nginx file and runs the certbot --nginx -d domain.com which generates the SSL for that domain. Right now there are around 200+ domains that had been created using the above script, which has stopped now.

Hello Everyone,

Did you guys find any solution to fix this issue?

Hi @harshshah8996

I don't see a Letsencrypt relevant problem.

Sounds that this meta-script

is buggy and creates a wrong nginx config file. But that's a problem of that not working script, not a Letsencrypt problem.
