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:I have to purchase
I ran this command:
It produced this output:
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
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):
This is a pretty broad question, and I think the only way I can really answer (if you don't know your domain, hosting provider, or web server software yet) is by linking to the documentation. There's a bunch of information there under "Overview" which I think may be what you're looking for.
From your video it looks like once you have your certificate from Let's Encrypt you paste it in the box then download the CA bundle and paste it in the other box.
We not have certificate this is the process to aad certificate to our web site but we don't know how to get CA bundle we have to add in this process shown in video we dont know how to get it
I only operate through this community. You can usually get all the help you need here, but you must make your questions clear and provide the needed information.
