I creating website default on plesk obsidian windows server. When install ssl letsencrypt for domain error status: 400.

Hi @tannguyen,

As @rg305 pointed out, your website must work in the first place, before you will be able to issue a certificate using Plesk.

Currently, trying to visit your website just fails:

$ curl -i  http://ssl.tadutest.com
curl: (56) Recv failure: Connection reset by peer

Until you fix that, you won't be able to get a certificate.

If you are unsure how to fix this problem, asking your web host or Plesk for support might be good next steps.
