Let's Encrypt validation status 400 unable to update challenge

Pleas check /var/log/hestia/LE-xxxxxx.xxxxx.xxxxx.log

And check the errors why it is not working

Common issues:

  1. Error in a other template for nginx ( run nginx -t )
  2. Proxy is disabled → Enable proxy and try again
  3. CF / Or other Proxies

To check the reason:

cat LE-jaap-mail.xxxxx.nl-20210422-003139.log
Go to step 3:
“challenges”: [
{
“type”: “http-01”,
“status”: “pending”,
“url”: “https://acme-v02.api.letsencrypt.org/acme/chall-v3/xxxxxx/UniqueID”,
“token”: “UniqueID”
},

Follow https://acme-v02.api.letsencrypt.org/acme/chall-v3/xxxxxx/UniqueID in your browser. You are able to see what IP it has been using
