Can't generate let's encrypt certificate on all domains SSL Error

[Justinas]

Hello,
when I try to generate Lets Encrypt certificate on all domains DA throws an error:

Cannot Execute Your Request​

Details 2021/10/08 14:16:19 Could not create client: get directory at 'https://acme-v02.api.letsencrypt.org/directory': Get "https://acme-v02.api.letsencrypt.org/directory": x509: certificate signed by unknown authority Certificate generation failed.​

I ran commands:

./build update
./build letsencrypt
./build lego
./build apache

But an error stays the same.

apt install ca-certificates -y
cd /usr/local/directadmin/scripts/
./letsencrypt.sh request_single my.server.com 2222
