I have a home webcam server that I want to access via https. Thus, I’m trying to set up a LetEncrypt certificate. My internet provider (Comcast) provides a non-static IP address and blocks port 443, so I have to use an alternate port and route through a DDNS service (Dynu).
I’m thinking I need to use certbot’s DNS verification to achieve this, and have executed the following command on my server…
sudo certbot certonly –manual –preferred-challenges dns
I specified nelsamia.com for the domain, and created a TXT record in the DNS with the text…
I get an error saying “No TXT record found at _acme-challenge.nelsamia.com”
Where am I going wrong?
