Hi, while installing netmaker server caddy failed due to certificate error.

{
  "level": "error",
  "ts": 1681589792.6725178,
  "logger": "tls.obtain",
  "msg": "will retry",
  "error": "[dashboard.netmaker.sysq.dev] Obtain: [dashboard.netmaker.sysq.dev] solving challenge: dashboard.netmaker.sysq.dev: [dashboard.netmaker.sysq.dev] authorization failed: HTTP 0  -  (ca=https://acme.zerossl.com/v2/DV90)",
  "attempt": 6,
  "retrying_in": 1200,
  "elapsed": 1247.399203361,
  "max_duration": 2592000
}

I thought there will be 90 days of free certs, anyone knows how to solve this or I will go to auto generated domain ?
