  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Resolved Let's Encrypt extensions and IPv6

Sorry for my English

Good afternoon. Tell me how to solve the problem with the automatic update of SSL certificates Let's Encrypt when the domain has both IPv4 and IPv6 simultaneously. If I delete the IPv6 record, the certificate is updated quietly
 
Perhaps IPv6 is not working on your server since IPv6 kernel module is not loaded and not available at all. Check it with:

#modinfo ipv6
modinfo: ERROR: Module ipv6 not found.

The LetsEncrypt server is trying to validate domains through IPv6 as it is a preferred protocol. As a solution, you can either completely remove IPv6 addresses from the network interfaces in order to perform token validation through IPv4, or configure IPv6 properly.
 
This is not a solution. Again, when I write AAAA domain - Let's Encrypt - it works fine, when writing A - Let's Encrypt works fine, and if you record A and AAAA at the same time - Let's Encrypt does not work.
 
IPv6 module is a part of Linux kernel. Your kernel should be compiled with this module. Make sure that you have default kernel from OS vendor where IPv6 module is already compiled by default in most cases.
 
I now do not understand, I have installed debian 8. By IPv6, the connection goes quietly. Works without problems. The network goes, you can get on it, and everything on IPv6. But when a domain name is registered simultaneously records A and AAAA, then certificates are not put. By doing this manually, I can safely install certificates. Automatic updating does not work.
 
The error was present in:
Tools and settings -> IP addresses -> IPv6 address should have been written not clean 2a03: xxxx: xxxx: xxxx :: xx
but 2a03: xxxx: xxxx: xxxx :: xx/64

Despite the fact that it shows 2a03: xxxx: xxxx: xxxx :: xx/48

Thanx
