I'm able to access all but one web page on the Internet.

Question:

I'm able to access all but one web page on the Internet.

Cause:

This issue could be caused by any of the below possibilities.

1. Web site down or other web page error.
2. Malware or other security settings blocking address.
3. Your IP address is blocked by the web site.
4. Issue with DNS servers and/or ISP.

Answer:

Note: Security settings setup by an admin at a school, work, library, or business can prevent you from accessing certain types of web pages. This document and Computer Hope will not help users get around these security measures. This document is meant to help home users or users who've been able to access a page but is no longer able to.

Website down

If the server hosting the website is down, you and anyone else trying to access the page will be getting errors. To quickly identify if the site it is up, use the Computer Hope Is it up tool. Using this tool you can enter the web address to quickly identify if the page is up.

If the page is up but you're unable to access it, continue reading through the suggestions below for help with resolving this issue. If the page is down we suggest giving the site a few hours to recover.

Web page or server hosting web page issue

If you're getting a 404, 500, 501, or other HTTP error, make sure that error is relating to the page not being found, and not an error that is related to something wrong with the server.

A full listing of HTTP error codes can be found here.

Browser issue

In some situations Internet browsers can encounter problems that may prevent them from accessing some Internet pages. Make sure this is not a browser issue by closing all open browsers and then re-opening and trying to access the page again.

Malware or security settings blocking address

If your computer is running Microsoft Windows, certain types of malware can affect how your computer accesses the Internet, and what web pages it's able to access. We suggest you scan your computer for any malware using a free utility such as Malwarebytes.

DNS or other ISP issue

Finally, if you've tried all the above suggestions, and know the site is working for other users as mentioned in the first section, it's likely you're encountering an issue with your Internet Service Provider (ISP), DNS, or your network.

Broadband users

If you're using a broadband Internet connection, try the steps below before attempting to contact support.

1. Turn off computer.
2. Disconnect the power to your modem (e.g. cable modem) and if you have a network router, disconnect the power to that router.
3. When disconnected, give it a few seconds and re-connect the power to each device, then turn the computer back on. Doing this simple set of steps can often resolve a lot of connection related issues, especially for those using cable broadband to connect to the Internet.

Contact support

• If you're using an ISP to connect to the Internet, we suggest contacting your ISP for additional help and support.
• If you're on a school or corporate network, contact the admin of your network or your IT department.

Your IP address is blocked by site

Finally, if you've followed all the above steps, it's possible that if you're trying to access a web page such as social networking sites, forums, online e-mail pages, chat pages, etc., your IP address may have been blocked because of abuse you've done, or by someone else who may share the same IP address as you.

For situations such as this, you will need to contact the Webmaster of the site you're trying to access sfor additional help in getting the block removed.
