How do I fix the "403 restricted error" with the "openresty" message when trying to visit a friends' site on a custom domain linked through Webflow?

If you're encountering a "403 restricted error" with an "openresty" message when trying to visit a friend's site on a custom domain linked through Webflow, there are a few potential solutions you can try:

1. Clear Browser Cache: Start by clearing your browser cache and cookies, as this can sometimes resolve the issue. Often, browsers cache certain elements of websites, and outdated cached data can cause conflicts. Clearing the cache allows your browser to fetch the latest version of the site.

2. Disable VPN or Proxy: If you are using a virtual private network (VPN) or a proxy server, try disabling it temporarily and see if that resolves the issue. VPNs and proxies can sometimes introduce complexities and conflicts that result in "403 restricted error" messages.

3. Check DNS Settings: Ensure that the DNS settings for the custom domain are correctly configured. Log in to your domain registrar or hosting provider's account and double-check that the DNS records, such as the A record or CNAME, are properly pointing to the correct Webflow server IP addresses.

4. Verify Webflow Hosting: Make sure that the site is correctly set up for hosting in Webflow. Check the Webflow project settings and confirm that the custom domain is properly connected and set as the default domain. Additionally, ensure that the SSL certificate is properly generated and enabled for the custom domain.

5. Firewall or Security Settings: Contact the website owner and ask if they have any security measures or firewalls in place that could be blocking access from certain IPs or locations. They might need to review their security settings and whitelist your IP address to resolve the issue.

6. Contact Webflow Support: If none of the above solutions work, it's best to reach out to Webflow support for further assistance. They have access to specific logs and technical details that can help identify and resolve the "403 restricted error" with the "openresty" message.

Remember to provide specific details, such as the exact error message and steps you've already taken when reaching out to Webflow support. This will help them assist you more effectively in troubleshooting and resolving the issue.
