There are many things that cause your site to be inaccessible. The article below will explain how to find out the cause of the problem if error messages such as "404 Not Found", "403 Forbidden", "500 Internal Server Error" and so on appear on the browser screen. Some things to check when your site is difficult to access are:
- Setting DNS and nameservers for your domain name.
- Domain name that has expired/expired
- Empty "index" file or missing "index" file
- Network/internet connection problems
- Your computer's IP is blocked by a firewall
- Your computer is attacked by ARP Spoofing/trojan/virus
- There is an error with the .htaccess file
DNS setting error
Errors in DNS or nameserver settings can cause your website to be inaccessible. Generally a website cannot be accessed within a few hours or a few days after a DNS change. Even though the DNS settings are wrong, the website can still be accessed within a few hours, but suddenly it can't be accessed after some time.
Solution:
Fix your DNS via cpanel control panel. To change the nameservers, please enter your domain panel (not cpanel).
Index file (index.html, index.htm, or index.php) Out of place or missing content (empty)
When a visitor accesses your website, the web server will try to open one of the following files: index.html, index.htm, index.php (the web server will look for the existence of these files in that order). If one of these files does not exist, the web server will display an error such as an error document, No Index file, or the web server will display a list of all files and filders in your account.
If the index file is empty (no contents) the internet browser program will display a blank page. If your index page is index.php, then the appearance of a blank page can also be caused by an error in your index.php file and the web server has been set to display a blank page if an error occurs in the processing of the php file.
Solution:
Check your index file, whether it is in public_html or not, or whether it is empty or not.
Domain name has expired or expired
If the domain is not renewed, it will enter an expiration period, where the domain is locked and redirected to a page called domain parking. After the expired domain expires, a domain will enter the deleted period, at this time the domain is still possible to be restored but at a high cost. If the domain is not renewed for too long, it will not be able to be renewed forever, but some domains can be purchased again by others.
Solution:
Immediately renew your domain, before the time period we specify. The expired domain renewal process takes 24-72 hours.
Internet Connection Problem
Maybe at some point you experience problems connecting the internet to the server where your website is located. This means, when that happens, you can still access other sites but your own site cannot be opened.
The first thing you will do is check the connection from your computer to the web server where your site is located using a command like "ping" available on your computer.
Open Command Prompt, type ping www.domain.com
If the result shows multiple "reply" lines, the connection to your web server is not a problem. The time shown in the result of the ping command indicates how fast the connection to your web server from your computer is.
If you see a "request timed out" error, it's likely that something went wrong somewhere between your computer and the server.

If you can't open all websites including www.google.com, please contact your ISP or internet connection provider.
Your IP is blocked by the server
Maybe one day you can't open all websites on our server, it could be because your IP is blocked by a firewall.
There are several causes of IP blocked firewall:
- Wrong login cpanel/webmail/ftp/ssh/pop3/imap many times
- Refreshing browser too often
- Spam
- Hacking
- DOS attack
- port scan
Solution:
Please report to our support at [email protected] by including your IP address. To find out what your IP address is, you can check here: http://whatismyip.com
Your computer is attacked by ARP Spoofing/trojan/virus
There are many viruses/spyware preventing you from using the internet connection. Actually there is a connection on your computer, but the virus blocks it.
Solution:
Scan your computer for viruses / spyware / trojans with the latest antivirus.
Error in .htaccess file
Writing errors in the .htaccess file can cause the website to become inaccessible by generating an error 500 Internal Server Error. It could also be because the htaccess configuration is not recognized by the server.
Solution:
Check your .htaccess file. If you just edited it, try reverting it back to how it was.
You can also search for references on google for htaccess configuration codes.
Additional Tips
- Check your internet connection, whether you can access to other web or not.
- Ping your domain using Command Prompt: ping -t www.domain.com
- Use the tracker facility from http://tools.pingdom.com/ping/ to check your website.
- Clear your browser cache, there is a possibility that you are still saving your old web pages that have not been updated.
- If the problem is still not resolved, you can check using another ISP or other network. The way to find out is like this: For example, if you can access the web from your home internet connection, but you can't access it from your work internet connection, then the problem is the office ISP and there is no problem on the server, or the office IP is blocked.
- Contact your internet connection provider (ISP).
- Restart your modem and computer and scan for viruses, there is a possibility that your computer has a virus that sends attack packets to the server so that your IP is blocked.
Refresh your browser, use the latest version of the browser and always be updated. Force refresh by pressing CTRL and F5 keys.
If the problem is still not resolved, please contact us, there may be server overload, high traffic, maintenance, repair, your IP is blocked by our server firewall and other unexpected things. We are always happy to help you.
