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. [crt.sh | example.com](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: [api.rajshriplastiwood.com](http://api.rajshriplastiwood.com) I ran this command: `sudo certbot --nginx -d api.rajshriplastiwood.com` It produced this output: \> Saving debug log to /var/log/letsencrypt/letsencrypt.log > Requesting a certificate for [api.rajshriplastiwood.com](http://api.rajshriplastiwood.com) > > Certbot failed to authenticate some domains (authenticator: nginx).

Sorry, I'm a bit new to this. What can/should I do? I've been waiting for 2 days for it to propagate. ---

There's nothing to "propagate", but you need your domain name to be working before you can get a certificate (or before anyone can access your web site). The `.com` nameservers say that your DNS server is `ns1.phpcloudserver.com` & `ns2.phpcloudserver.com` which are both (!) at 192.177.75.10. But that IP isn't actually responding. What you should do is configure your DNS servers with your registrar, and ensure that any glue records needed are correct. But we don't know what your correct configuration is supposed to be. ---

The domain name correctly points to the API and is working in the browser. I'm using cPanel to manage my domain, I tried reading the record. I tried checking on: [DNS Checker - DNS Check Propagation Tool](https://dnschecker.org/?camp_opt=exact_match#A/api.rajshriplastiwood.com) A lot of them are invalid, I'm unsure why. ---

The problem seems to be that [ns1.phpcloudserver.com](http://ns1.phpcloudserver.com) etc are not responding to UDP queries like a normal DNS server would (but they are answering on TCP). You could raise this with them (assuming you are not the administrator) or you could move to a different DNS provider like cloudflare etc. [edit, a yep, one of the "glue" records is a private IP] ---

> [@Aarav](#): > > A lot of them are invalid, I'm unsure why. Probably because of the wrong "glue" records as Peter noted earlier. From the DNSviz link he posted ![image](https://global.discourse-cdn.com/letsencrypt/original/3X/c/d/cdb77530e34fe4c6641432aab130102315e7ad57.png) For example, using the IP address for your ns1 name server works. But, using the IP in the glue record fails. This is the first thing you should fix ```nohighlight # Using IP in glue record dig +noall +answer A api.rajshriplastiwood.com @192.177.75.10 ;; communications error to 192.177.75.10#53: timed out ;; communications error to 192.177.75.10#53: timed out ;; communications error to 192.177.75.10#53: timed out ;; no servers could be reached # Using IP from DNS for ns1.phpcloudserver.com dig +noall +answer A api.rajshriplastiwood.com @103.131.24.11 api.rajshriplastiwood.com. 14400 IN A 31.97.61.130 ``` You can easily reproduce this DNS query problem using [https://unboundtest.com](https://unboundtest.com) ---
