Problem with a Single Site. Is It Network-Related?

I experienced a problem yesterday while working on a client's laptop that's perplexed me. My customer asked me to install an email client on his Windows 7 laptop so that he could avoid using Time Warner Webmail. I installed Windows Live Mail 2012 (WLM) and entered all Time Warner's recommended settings including my client's email address and password. WLM failed in every attempt to download his mail.

In order to make certain that I had been given an accurate ID and password, I decided to logon to Time Warner's Web Mail site (https://mail.twc.com) and test the ID and password. Every attempt to get to this website where Time Warner clients enter their ID and password resulted in my seeing "This page can't be displayed"; "This page is not available" or "The connection was reset" (depending on whether I used the latest version of IE 11, Chrome, or Firefox). Time Warner assured me the site was not down. A friend who lives close confirmed this by accessing the site with no difficulty. Whether I entered "mail.twc.com" or used a Time Warner link that existed to take me to this site, my result was the same. After speaking with Time Warner for more than an hour, I decided to have my client try the laptop in his home. When my client launched WLM at his home, it worked flawlessly!

While I no longer a need to access this site, I'd like to understand why this problem persists.

The following may be helpful.

- My Windows 7 Troubleshooter identifies no problems after failing to access the site
- Results identical with Chrome, Internet Explorer 11, Firefox
- Problem persists after cookies deleted
- Problem persists when antivirus (Avast Free) disabled
- Problem persists when firewall (Windows) disabled
- Host file inspected and found to be clean
- Problem persists after router turned off for 30 seconds and then rebooted
- Problem exists when using a wireless connection or a wired connection
- Problem exists on every PC tested in my home
- My PCs are clean. They are scanned multiple times each week with Avast. Malwarebytes finds nothing suspicious.

I'm assuming the problem must exist somewhere in my network because the problem seems limited to my PCs. I'm not aware of any other website that is inaccessible. I'd appreciate any suggestions for identifying why this problem exists and how to address it.

Are you able to access using the following?

https://107.14.73.68/

If so, I would suspect an issue with the DNS you are using.

No, I can't access the site by using the IP address. However, I just determined I can access it by using the Tor browser which of course changes my IP address. Is it safe to assume that my IP address may be blocked by Time Warner?

That's interesting. I'd find it strange if your ISP was blocking access, but it's not out of the question.

Have you tried pinging mail.twc.com, or performed an nslookup?

You might also try https://webmail.twc.com/

If you have a separate modem and router, I would recommend trying to access when connected to only the modem (after properly rebooting it).

If you still have problems, it is likely that the TWC mail server is for some reason blocking your IP address. You may need to have your ISP or TWC investigate further.

My router qnd modem are not separate. I'm pretty certain at this juncture that Time Warner or as you suggest, possibly my ISP is blocking my access to their site.
