Unable to set Let's Encrypt for control panel


I failed to set up Let’s Encrypt for control panel

~# v-change-sys-hostname hostname.domain.tld
~# v-add-letsencrypt-host
Error: DNS record for hostname.domain.tld127.0.0.1 doesn’t exist
Error: Let’s Encrypt SSL creation failed

In the page https://hostname.domain.tld:8083/list/web/ there are two domains:

  • hostname.domain.tld
  • hostname.domain.tld127.0.0.1

Even though hostname.domain.tld127.0.0.1 was removed from the web list, setting Let’s Encrypt for the control panel also doesn’t work.

Additional information, I’m using Debian 11 with 1GB RAM, 1GB SWAP and 2 CPU Cores which I use for DNS Cluster purposes.

I’ve also tried with different OS, like Ubuntu 18.04 and Ubuntu 20.04. But I experienced the same thing.

What happens when you run:

nslookup hostname.domain.ltd

Thank you for the response. It’s as you asked:

~# nslookup hostname.domain.tld

Non-authoritative answer:
Name: hostname.domain.tld
Name: hostname.domain.tld
Address: 2a01:0ab0:e:0b1::c2d3
Name: hostname.domain.tld
Address: 2b02:c123:456:0ab::123c

Be sure to do the nslookup on the hestia host, which has the issue. Also be sure, u dont use any ipv6 records, also, if you use cloudflare, port 8083 isnt supported from them.

Currently the ipv6 record does exist at hostname.domain.tld, however I’m not using cloudflare.
I’ll try again installing hestia with another new server, without ipv6 records. I will explain the results here.


On another fresh server, before installing hestia I checked ipv6

~# nslookup slave02.domain.com

Non-authoritative answer:
Name: slave02.domain.com

IPv6 has also been disabled. I think this is also what I need to prevent unwanted communication.

~# nano /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Even i removed the ipv6 line from the file /etc/network/interfaces. But after finished installing hestia, on the control panel page https://slave02.domain.com:8083/list/web/ still loading two webs

What happens when you run:

hostname in command line?

It sounds like it is as:


As if it doesn’t exists it will create it…

Also what is the contents of /etc/hosts

I forgot this file

I removed the slave02.domain.com127.0.0.1 line in the file /etc/hosts, now I can run v-add-letsencrypt-host

Thank you for your response
