ZeroSSL Verify API cannot verify and shows me all certificates info

[SaeedFazlollahzadeh]

Hi, let me give an example of my failed task to test ZeroSSL API:

This is my generate.sh file which is the first step and works fine:

# source /home/zerossl/ZEROSSL_KEY.sh # let me add variables here for github
ZEROSSL_KEY=MyZeroSSLAPIkey
DOMAIN=1.1.1.1 # My IPv4
openssl req -new -newkey rsa:2048 -nodes -out "$DOMAIN".csr \
            -keyout "$DOMAIN".key \
            -subj "/C=US/CN=$DOMAIN" \
            &>/dev/null
curl -sX POST https://api.zerossl.com/certificates?access_key="$ZEROSSL_KEY" \
        --data-urlencode certificate_csr@"$DOMAIN".csr \
        -d certificate_domains="$DOMAIN" \
        | jq > generate.txt

This is the first step and I see in https://app.zerossl.com/certificates/draft one.

But the issue is with other APIs. I manually create a file in /var/www/html/.well-known/pki-validation/SOMEFILE.txt and add the required text there. So it's accessible via 1.1.1.1/.well-known/pki-validation/SOMEFILE.txt.

When I want to call Verify API:

source /home/zerossl/ZEROSSL_KEY.sh
curl -s -X GET -d validation_method='HTTP_CSR_HASH' \
"https://api.zerossl.com/certificates?access_key="$ZEROSSL_KEY"&="$ID"/challenges" \
| jq > verify.txt

This is the output:

    {
      "id": "SOMEID
      "fingerprint_sha1": null,
      "brand_validation": null,
      "validation": {
        "email_validation": {
          "1.1.1.1": []
        },
        "other_methods": {
          "1.1.1.1": {
            "file_validation_url_http": "http://1.1.1.1/.well-known/pki-validation/84CE1466F4209BF8868B311366FACA20.txt",
            "file_validation_url_https": "https://1.1.1.1/.well-known/pki-validation/84CE1466F4209BF8868B311366FACA20.txt",
            "file_validation_content": [
              "86C1657D6F8C41B64852B2B1F6BC878C92EA6B51E20634AE25F72A917791FB83",
              "comodoca.com",
              "6f73bcce63a9615"
            ],
            "cname_validation_p1": "_84CE1466F4209BF8868B311366FACA20.1.1.1.1",
            "cname_validation_p2": "86C1657D6F8C41B64852B2B1F6BC878C.92EA6B51E20634AE25F72A917791FB83.6f73bcce63a9615.comodoca.com"
          }
        }
      }
    }
  ]

While it should verify domain, it does not.
I'm sure that http://1.1.1.1/.well-known/pki-validation/84CE1466F4209BF8868B311366FACA20.txt is accessible and has the contents of file_validation_content.
Am I doing anything wrong here?
