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), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: kai.com
I ran this command: nginx -t
It produced this output:nginx: [emerg] unknown directive "ssl_early_data" in /etc/nginx/conf.d/default.conf:32
nginx: configuration file /etc/nginx/nginx.conf test failed
My web server is (include version): 192.168.242.181:8065
The operating system my web server runs on is (include version):red hat 8.7
My hosting provider, if applicable, is:
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): 1.22.0
I would also recommend that you not use the domain name kai.com. I know from your prior thread this name does not belong to you. While it is technically possible to use such names on your own private network you won't be able to use this if/when you choose to use it on the public internet.
Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
Thus you need to own and have control over the Domain Name (or have a subdomain under an existing domain name, for example pointed to your server by your employer or school) you wish to obtain a certificate for, from an ICANN Accredited Registrar.
Since these are Domain Validation (DV) certificates the Domain Name System (DNS) is used extensively in the validation process as well a allowing us to assist here on Let's Encrypt community.
DNS Queries need to give consistent results from any location on the Internet, all your authoritative DNS Servers for the Domain need to also give consistent results as well.
