Hello there, I am having trouble accessing my website's address bar. Instead of being directed to port 80, it seems that the client is being redirected to port 443. As a DNS hosting owner, could you please advise me on how to register this issue? Thank you very much in advance for your help!
DNS is not the solution for this problem. When accessing the https version of a site, it's important to provide a tricky header, such as "Strict-Transport-Security: max-age=31536000; includeSubDomains," to ensure that only https is used. One can also add the domain to the Predefined list of HOSTS sites, which can be downloaded by browsers and used exclusively for https. This feature is supported by Chromium engines, but not all browsers.
When accessing a website through its secure https version, it's important to use a specific header called "Strict-Transport-Security" to ensure that only https is used. Additionally, one can also add the domain to a predefined list for exclusive https access. It's important to note that this feature is only supported by certain browsers. Understanding these technical details can help in ensuring safe and secure web browsing experiences.
Your hosting includes a website called zzz.com, which has a redirect set up to https://zzz.com. The https version includes a hosts header to ensure that the client browser recalls that it must use https. As a result, the browser initially goes to the http version before being redirected to the correct version and remembering to use https in the future. DNS's main function is to provide the IP address for the domain name to be connected to. This is a basic explanation of how this process works.
client browser is redirected from http to https via a hosts header, and how DNS provides the necessary information for the connection. This is important information for anyone running a website or who is involved in the technical aspects of website management.
As a DNS hosting owner, you can help troubleshoot this issue by checking the DNS records for the domain in question. Here's how you can register the issue and provide assistance:
1. Review DNS Records: Verify the DNS records for the domain to ensure that the correct A (IPv4 address) and AAAA (IPv6 address) records are pointing to the intended web server IP address on port 80.
2. Check for HTTPS Redirection: Confirm if there is a HTTPS redirection in place on the web server or any load balancer that could be causing the traffic to be directed to port 443 instead of port 80.
3. SSL/TLS Certificate: Check if there is a valid SSL/TLS certificate installed on the web server for port 443. If there is, ensure that it doesn't enforce HTTPS redirection without proper configuration.
4. Customer Support: Provide clear instructions to your customer on how to verify these settings on their web server. Offer to assist with any necessary changes to the DNS records or provide guidance on configuring the web server to handle HTTP traffic on port 80 and HTTPS traffic on port 443.
5. Network Configuration: Check for any network devices (e.g., routers, firewalls, proxies) that might be causing the redirection. Ensure that these devices are not intercepting and redirecting the traffic to port 443.
6. Communication with Web Hosting Provider: If the web server is hosted by a third-party provider, reach out to their technical support team to investigate if there are any server-side configurations or redirects that could be impacting the traffic flow.
7. DNS Propagation: Make sure that any recent changes made to the DNS records have fully propagated across the internet. Sometimes, delays in DNS propagation can cause unexpected behavior.
8. Troubleshooting Tools: Provide instructions on using tools like `nslookup` or online DNS lookup services to verify the resolved IP address for the domain and confirm that it matches the intended web server IP address on port 80.
By taking these comprehensive steps and offering diligent support, you can effectively assist your customer in diagnosing and resolving the issue related to the redirection from port 80 to port 443 when accessing their website's address bar. It's important to communicate clearly and provide detailed guidance throughout the troubleshooting process.
This typically occurs when your server is configured to force SSL connections on port 443, which is standard for secure traffic. First, check your .htaccess file or server configuration for any rewrite rules that might be redirecting HTTP requests to HTTPS. If you want users to access your site on port 80 without redirection, you'll need to modify these settings.
Additionally, ensure your DNS records are correctly pointing to your server's IP.
By encrypting DNS queries, moving to HTTPS DNS hosting enhances security and privacy. For enhanced security, use DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT). Google (8.8.8.8) and Cloudflare (1.1.1.1) are well-known providers. Update your domain's nameservers to reflect your registrar's support for HTTPS-based DNS. Use dig or nslookup to test changes.
