Server returned error code: 3: name error

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:
https://buildly.recrm.io
I ran this command:
We are using openresty lua auto ssl docker, we hit https://buildly.recrm.
It produced this output:
Your connection is not private

Hi @prudhvi

I don't see a name error. I see a

Invalid response from http://buildly.recrm.io/.well-known/acme-challenge/BcV_kJuut2fgTI-5PUmvhFAEJ_AVTgtyxYGBmjsbp30

404 Not Found

error.

So Letsencrypt can't get your validation file. But checking your domain via buildly.recrm.io - Make your website better - DNS, redirects, mixed content, certificates , I don't see a real problem:


Domainname Http-Status redirect Sec. G
http://buildly.recrm.io/
13.232.99.128 200 0.480 H
https://buildly.recrm.io/
13.232.99.128 200 10.100 N
Certificate error: RemoteCertificateNameMismatch, RemoteCertificateChainErrors

13.232.99.128 404 0.360 A
Not Found

The 404 is ok, the file doesn't exist. Do you have wrong redirects? Or does your client find the right directory to save the file?

There is a warning:

err: # !! WARNING !! Extra configuration directory /etc/resty-auto-ssl/letsencrypt/conf.d exists, but no configuration found in it.

But I don't know the details of this client.

Hi JuergenAuer,

Thanks for your reply, we sought out the issue.

Thanks & Regards,

Prudhvi.
