I set up an Ubuntu server on virtual-box and installed nginx. Additionally, I obtained a "real ip" from a provider and registered a pp.ua domain.

To switch to a virtual machine using the domain name, I am attempting to connect to nginx on the virtual machine from my desktop. However, I am facing difficulties.

Could the ns server be causing issues in this process? It seems like the signal is not passing beyond the router. When I try to access the domain name through my browser, it redirects to 192.168.1.1 and opens the admin panel of the router instead.

In order to properly configure a domain to work with a virtual server, you need to have access to zone management and IP association capabilities, which are typically provided by the domain registrar. Additionally, it's important to ensure that the virtual server is configured to bind the assigned IP with the domain name, which can sometimes be overlooked in the /etc/host file.

To successfully set up the server, it's recommended to initially test its response from the machine on which the server is installed, before attempting to access it from other machines. To do so, you will need to obtain a white IP from an internet provider and redirect incoming traffic to the virtual machine.

Finally, don't forget to adjust the A-record of the domain name to lead to your white IP-provider. By completing these steps, your PC will be able to redirect incoming traffic to the virtual machine, allowing for seamless access to your server.

The host file is actually an operating system (OS) file, not a server file. It's important to note that the concept of a server is quite broad, ranging from physical hardware located thousands of kilometers apart to various software, including server operating systems, HTTP servers, ftp servers and so on. There are also different types of protocols and address data like DNS servers, IP servers for telephony, and more. Essentially, a server is an active network unit that can respond to requests without human intervention, and it encompasses all modern developed systems, including client ones.

To ensure the virtual machine works as a server, it's important to clarify how its network connection is set up. The best option, in terms of simplicity, is a network bridge. This will enable the virtual machine to directly listen to the external network, allowing for easy configuration of the server and server OS running inside the virtual environment.

On the other hand, it's also possible to deploy a proxy server in the base OS. This will help filter traffic and redirect only the necessary requests to the virtual machine, which is another viable alternative.

To send a domain to your VPS, the easiest way is through an A-record. Start by finding the IP address of your VPS and deleting all existing A-records that have @, www, or cloudflare-resol-to in their name. Then, add two new A-records with the following information:

A-entry 1: Name - @; Indicates - The IP address of your VPS; TTL - Default
A-entry 2: Name - www; Indicates - The IP address of your VPS; TTL - Default

Alternatively, you can use a combination of A- and CNAME-records. Again, start by finding the IP address of your VPS and deleting any existing A-records with @, www, or cloudflare-resol-to in their name. Then, add the following A- and CNAME-record:

A-record: Name - @; Indicates - The IP address of your VPS; TTL - Default
CNAME record: Name - www; Indicates - Your domain name (for example, domen.com); TTL - Default

If you want to use your own name servers (e.g., ns1.domen.com and ns2.domen.com), then the option with child name servers may be more appropriate. To do this, ensure that your VPS has a working DNS zone and create child name servers before changing your current name servers to the new ones. Note that any changes to DNS records will trigger the delegation process, which can take up to 24 hours.

It is possible that the issue lies with the configuration of your DNS server (ns server). Here are a few steps you can follow to troubleshoot the problem:

1. Check the DNS settings: Ensure that your domain name is correctly pointed to your virtual machine's IP address in the DNS settings. You can do this by logging into your domain registrar's website and accessing the DNS management section.

2. Check the router settings: Verify that the port forwarding rules on your router are correctly set up to forward incoming traffic on port 80 (HTTP) and/or port 443 (HTTPS) to your virtual machine's IP address.

3. Test the connection: Use a tool like `nslookup` or `dig` from your desktop command line to check if the DNS resolution is correctly pointing to your virtual machine's IP address. For example: `nslookup your-domain-name.pp.ua`. If the resolved IP matches your virtual machine's IP, then the DNS setup is correct.

4. Check the firewall settings: Ensure that any firewalls, both on your virtual machine and your router, are not blocking incoming traffic on ports 80 and 443.

5. Verify nginx configuration: Double-check your nginx configuration file (`nginx.conf`) to ensure that the server blocks are properly set up. Make sure that the `server_name` directive is correctly set to your domain name.

6. Restart nginx: After making any changes to the nginx configuration, it's important to restart the nginx service for the changes to take effect. You can do this by running the command `sudo service nginx restart` on your virtual machine.

7. Check server logs: Examine the nginx error logs (`/var/log/nginx/error.log`) on your virtual machine to see if there are any relevant error messages that could point to the root cause of the issue.

8. Temporary disable local DNS cache: Sometimes, your desktop might be caching DNS entries locally. To rule out this possibility, you can try temporarily disabling or flushing the DNS cache on your desktop machine.

9. Test from a different network: If possible, try accessing your domain name from a different network, such as using your mobile phone's cellular data or connecting to a different Wi-Fi network. This can help determine if the issue is specific to your current network or if it is more broadly related to the DNS configuration.

10. Seek assistance: If you've followed all the troubleshooting steps and are still experiencing difficulties, consider reaching out to your domain registrar's support or seeking assistance from forums or communities specific to web hosting or networking. They may be able to provide further insights or guidance based on your specific setup.

11. Check network settings on the virtual machine: Verify that the network settings on your virtual machine are configured correctly. Ensure that the virtual machine is using Bridged Adapter or NAT network mode, so it can communicate with the external network.

12. Test connectivity using IP address: Instead of accessing your domain name, try accessing your virtual machine directly using its IP address from your desktop browser. For example, type `http://<virtual-machine-ip>` in the browser's address bar. If you can access the nginx server using the IP address, it indicates that the issue is related to DNS resolution or routing.

13. Temporarily disable router's admin panel: If accessing the router's admin panel shows up when you try to access your domain, temporarily disable the router's admin panel and try accessing your domain again. This will rule out any conflicts between the admin panel and your domain.

14. Check DNS propagation: DNS propagation can sometimes take time, especially if you've recently made changes to your DNS records. Use online tools like "DNS Propagation Checker" to verify if your domain name has propagated globally.

15. Verify ISP restrictions: Some Internet Service Providers (ISPs) may block incoming connections on specific ports, such as port 80 or 443. Contact your ISP to inquire if they have any such restrictions in place.

16. Use external port checking tools: There are online tools, such as "Open Port Check Tool," that allow you to check if a specific port is open and accessible from the internet.

17. Check firewall settings on the virtual machine: Ensure that the firewall settings on your Ubuntu server allow incoming connections on ports 80 (HTTP) and 443 (HTTPS). You can check and modify the firewall rules using the `ufw` command line tool.

18. Verify port forwarding settings: Double-check that port forwarding is set up correctly on your router. Ensure that the external ports (typically 80 and 443) are being forwarded to the internal IP address of your virtual machine.

19. Test from a different device: Try accessing your domain from a different device connected to the same network. This can help determine if the issue is specific to your desktop machine or if it affects multiple devices.

20. Disable local DNS caching on your desktop: Temporarily disable any local DNS caching or clearing the DNS cache on your desktop machine. This can help ensure that you are retrieving the latest DNS information when accessing your domain.

21. Verify external IP address: Make sure that the "real IP" obtained from your provider matches the actual external IP address assigned to your router. You can check this by searching for "what is my IP" on a search engine and comparing it with the IP provided by your ISP.

22. Double-check DNS configuration: Confirm that the DNS records for your domain are correctly set up. Ensure that the A record, or CNAME record if applicable, points to the correct IP address of your virtual machine.

23. Verify domain registrar's DNS settings: Ensure that the DNS settings in your domain registrar's control panel are properly configured and match the IP address of your virtual machine.

24. Restart router: Try restarting your router to refresh its settings. Sometimes, routers can become unstable or encounter temporary issues that can affect network connectivity.

25. Check if the IP address is publicly accessible: Use an online port-scanning tool to check if ports 80 and 443 on your virtual machine's IP address are open and accessible from the internet. This can help identify if the issue is specific to your network setup or if it is related to the configuration of your virtual machine.

26. Temporary disable any VPN or proxy connections: If you are using a VPN or proxy connection on your desktop machine, temporarily disable it and try accessing your domain again. Sometimes, these connections can interfere with your ability to reach your virtual machine.

27. Confirm DNS resolution on your desktop: Open a command prompt or terminal on your desktop machine and run the command `nslookup your-domain-name.pp.ua`. Verify that the correct IP address is being resolved for your domain name. If not, it may indicate an issue with the DNS configuration.

28. Verify external access to your router: Try accessing your router's admin panel remotely using its public IP address and the appropriate port number (e.g., http://your-public-ip:admin-panel-port). If you can access the router's admin panel remotely, it suggests that port forwarding is not properly configured.

29. Temporary disable any local firewall or security software: Temporarily disable any local firewall or security software running on your desktop machine. These can sometimes block access to certain ports or interfere with network connectivity.

30. Test with a different web server: Try installing a different web server, such as Apache, on your virtual machine and test if you can access it using your domain name. This can help determine if the issue is specific to nginx or if it is more generalized.
