Create Let’s Encrypt SSL with Ubuntu

thanks brother

Hi I would like to thank you for this video. It helped me a lot to understand the whole process. However, I couldn’t get the certification. I am stuck in where I give a command ‘sudo certbot –nginx’ only to get this message,

‘Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Domain: {mywebsiteDNSaddress}
Type: unauthorized
Detail: {mypublicIPv4}: Invalid response from http://{mywebsiteDNSaddress}/.well-known/acme-challenge/5dEpVAqj-vwefebG7UXC_4MXhsdfefeLUuYZ0KrBY: 404’



You mentioned that the Ip address from ‘ip a’ has to be the same as ip address from ‘ping mywebsite.com’ at 0:24.
And I found that the IP address I get from command `ip a`, shown next to ‘inet’ was showing the Private IPv4 address not my public address.
So they didn’t match . 
If this doesn’t bother you too much I would like to ask you for an advice how I could solve this kind of situation. 

(I asked chatgpt and community and couldn’t find solution for this only to be lost in circles)

can you explain how to setup that domain name. i mean that when start you ping to the domain name but not tell me how you setup to ping

Im getting an Error about the port 80 being used.
