I tried installing SSL via keyhelp-toolbox and received the following error. I disabled IPv6, but now it won't update at all.

Certificate name: lin.saviorhost.com (Let's Encrypt)

Verification ended with an error.

Hello,

Let's Encrypt still gets the IPv6 via DNS. You have to wait until the DNS update is done worldwide
