Server is blocking sending tickets

I want to add a ticket form on my website (I am using Magento 1.9). The ticket form is from Zoho.
I have added the code:

<script type="text/javascript" nonce="{place_your_nonce_value_here}" src="" defer></script>

When I click on the submit button, I get this error in console:
Access to XMLHttpRequest at ‘’ from origin ‘’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.


I assume there is a server configuration that blocks sending the tickets.
Here are the headers from .conf file:

		Header always set Feature-Policy "autoplay 'none'"
		Header set Connection keep-alive
		Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure
		Header always set Referrer-Policy "same-origin"
		Header set X-XSS-Protection "1; mode=block"
		Header set X-Content-Type-Options "nosniff"
		Header set Access-Control-Allow-Origin "*"
		Header always set X-Frame-Options "SAMEORIGIN"
		Header set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" env=HTTPS
		Header always set Permissions-Policy "geolocation=(),midi=(),sync-xhr=(),microphone=(),camera=(),magnetometer=(),gyroscope=(),fullscreen=(self),payment=()"
		Header always set Content-Security-Policy "object-src 'none'; upgrade-insecure-requests;"

I don’t get it what is the problem and how to fix this.
