Unable to access certain HTTPS websites

This is a bit of an odd one.  I'm not a BT customer, but work in network operations for a number of companies.

 

  • I'm aware of a large body of BT Broadband customers who can't access various websites over HTTPS.
  • When they try and access the website the web browser just sits there saying connecting..and eventually just gives up.  No HTTP error codes etc. Just "The Connection Timed Out"
  • It's only effecting a few HTTPS sites, not all.  
  • DNS is working correctly, the domain name is being resolved to the correct IP address.
  • They can tracert/ping the server
  • They can access the websites by typing https://ip.address

I've spoken to BT Support on behalf of one customer but they weren't very intrested.

 

A couple of the sites people are having problems with:

 

https://www.rya.org.uk/Pages/login.aspx?ReturnUrl=/Pages/Home.aspx

 

https://apply.esher.ac.uk

 

I've also noticed that there have been quite a few old posts on these forums reporting the same issues. 

 

Is anyone else experienceing this problem? or does anyone know of any solutions?

 

Thanks

Daniel

Yes, same problem here, with a home hub 3. Some, but not all https websites - it's VERY annoying

Re: Unable to access certain HTTPS websites

Typing https://194.81.3.120 gives me a prompt that the certificate is not for that address

 

Following your link lets me access the site correctly.

 

I had similar bother to this some time ago and that was down to ActiveX, maybe a browser setting ????

 

I'm using Firefox.

 

Sorry can't be much help..  Smiley Sad

First off try different browsers. If you still have a problem with mutliple browsers it might be worth trying to change your MTU size, Try 1400 and then if no joy try 1200. You can find further information on changing MTU size here http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/how-do-i-change-the-mtu-settin...
