Cannot access one Website in BSNL Connection - Not Opening Some Websites

I can surely say today is one of my bad days because I never understood my ISP (BSNL) was the reason behind blocking one of my client's website in my office. I could even ping this website successfully but not able to open this website in any browser (I tried Firefox, Opera, Chrome and IE). I spend hours to troubleshoot this issue but the issue persists. I am not able to access one website via BSNL Internet connection but all other websites are fine. At first I thought it is my computer which is blocking the website and I wasted a lot of time by troubleshooting without knowing the actual reason. The error message we are getting while trying access this website via BSNL connection is "403 Forbidden -You don't have permission to access / on this server.Additionally, a 404 Not Found error was encountered while trying to use an Error Document to handle the request ". Only in BSNL connection we are facing this issue and we can access the same website via Tata broadband and Reliance connection. I called some other friend's who are using BSNL connection to verify the issue and they confirmed it. I tried to access the website via the IP address but it also failed (The website might be using shared IP address).

Steps I did to Fix the Issue of not able to access a website via BSNL Connection

I would like to share the steps I tried to fix the issue of not able to access my client's website with BSNL Internet connection.

1. Changed the Default BSNL DNS address

I changed the DNS address of my computer in a thought it might be the faulty BSNL DNS server which is preventing the website from opening in my computer. I changed the default DNS settings and set it to Open DNS address. I really hoped this will work but the issue persists and I failed to access this website through BSNL connection. Some of my previous DNS related articles are:

1. How to add Open DNS in Ubuntu Linux

2. How to configure Google DNS

2. Disabled Firewall and AntiVirus in my computer

There is a chance that a wrongly configured Internet Security suit can block a website in your computer. So I disabled all security programs in my computer but the issue persists.

3. Checked the host file and it is also fine

Any wrong entries in host file can block specific website in your computer. I checked for any new entries in host file but failed to find any issues there.

4. Results of Ping and Tracert operations

I can successfully ping the website from command prompt but tracert operation failed at first hop itself. It seems very strange for me. The screenshot is added below but I want to remove my client's website name from the picture.

My website is not opening in BSNL Internet connection

It seems BSNL modem itself is blocking the packets (from tracert test) to the specific website and that is why the website is not opening in BSNL Internet connection. Then how ping operation is working ??? I am very much confused at this point.

5. Accessing the blocked website via Proxy Server

Whenever I try to access this website via proxy servers, I can access the website. So it is clear that something from BSNL end is wrong and that is why I am not able to Access this website.

6. Reset browser settings and removed all unwanted pluggin

It seems my computer is able to communicate with the website (ping test) but browsers are not. So I reset the browser settings and removed all unwanted add-ons. This steps also failed.

7. Only BSNL is blocking this website

I double checked the issue with other ISPs (Reliance and Tata communication) and there is no issue in accessing the website.

8. I can access the website with Opera Turbo enabled (Updated Tip)

When I enabled Turbo I can access this website. Click here to see more details.

Experience with BSNL Customer Service

I called BSNL customer service for more assistance and they agreed the issue seems to be from BSNL only. They suggested me to perform following steps to access the website with BSNL connection.

1. Reset and Reconfigure BSNL Modem

We reset and reconfigure the modem but the issue persists. I couldn't able to access the website even after reconfigure the modem.

2. Bridge the BSNL modem and tried to access the website

MY BSNL modem is configured in PPPoE mode and we changed it to bridge mode. Though we bridged the modem, it also failed. So they gave me one of their supervisor's email address and requested to send him an email regarding this issue. Anyway I would like to add one thing, the BSNL customer care executive was very helpful and kind. Even though the issue is not fixed I would like to thank her for her efforts to fix the issue.

It is definitely a BSNL problem. I too cannot access my blog in my home. I am using BSNL data one connection. Can you tell me how to open my blocked blog ?

Yes you are right, I couldn't solve the issue but I tried most of the possible troubleshooting steps at user end.

The issue is 100 percent from ISP end and there was nothing much I could do. Even Technical Support guys were helpless. Anyway thanks for reading my blog and your kind comment.

Same problem here... I think BSNL blocks some IP ranges, thats why these sites doesn't open... I have a question, How to unblock such IPs from BSNL network?

Siju George said...

The only option is to contact BSNL technical support and ask then to fix the issue. As a temporary solution we can use proxy software to bypass this filtering.
