Moved to Digital Ocean and there I can ping the new ipv6 using http://www.ipv6now.com.au/pingme.php and I can also get whois data and so on using https://www.ultratools.com/tools/ipv6Info , but I still get the same Let’s Encrypt Error. And ipv4 gets an app error in the browser, but ipv6 cannot be reached. So I am starting to wonder if this a server issue or an app issue… Or is it because I am on an ipv4 network and so is the Laravel Forge site trying to generate the certificate?
