our Let’s Encrypt expired this morning and the website is showing error note (not private)
please advise how i can renew it again, i made some searches here but i couldn’t understand anything.
And i found the reason that we blocked the HTTP connection this is why, so please help.
we use digital ocean
Unblock HTTP and rebuild, shutting down :80 isn’t supported. It’s used to verify the request for the certificate and once the certificate is issued it’s responsible for redirecting users to HTTPS. NGINX listens on both ports, so shutting :80 down doesn’t make the machine more secure.
You can’t issue a certificate via Let’s Encrypt with port 80 blocked.
