Unable to use shortened links from bit.ly on BT broadband

bit.ly is a link shortening service widely used on Twitter and other platforms. For a number of weeks now I have been unable to access any https://bit.ly/ URLs from my BT fibre connection.

In Chrome I get the following error:

This site can’t provide a secure connection

bit.ly uses an unsupported protocol.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

 

In Firefox I get the following error:

Secure Connection Failed

An error occurred during a connection to bit.ly. Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

 

This can be reproduced on all devices on my BT connection, wired or wireless. As soon as I use another provider, the problem goes away and I can successfully access bit.ly links.

If I perform a DNS lookup then bit.ly resolves to 81.130.111.239 on my BT connection, which is a BT owned IP. From outside of BT, for example via CloudFlare or Google DNS, it resolves to 67.199.248.10 and 67.199.248.11.

I have also seen a handful of similar reports on Twitter where people report the same error messages when trying to access bit.ly links. I wonder if this is some kind of network level blocking or filtering that is somehow misconfigured?

Do you have BT Parental Controls enabled?

That was causing the issue for me.

I logged into My BT, and added http://bit.ly the My Allowed websites section and I can now access bit.ly links again

Hi @Shevek,

Thank you for posting that's a good suggestion.

@longwave If you have Parental Control can you Try adding that link to your allowed list?

Thanks

Hi, Thanks for that. The parental controls safe site add worked for me too.

But, this surely is a problem with the recent router upgrade. The BT engineer hadn't heard of it at all and didn't seem to know anything about it until I pointed him to this thread here. ho hum. Not good

Router upgrade?

Are you referring to your Home Hub or a BT side router?

If its the Home Hub, I can confirm that it's nothing to do with that - I have never used one, I have TP-Link VDSL router and still had the issue.

Its not a hub problem, its a parental controls network problem.

I didn't have Parental Controls on, but still hit this problem.

I was advised to switch off "Web Protect" (In account settings) until they have fixed the problem.

Re: Unable to use shortened links from bit.ly on BT broadband

Interestingly you can get rid of the problem by turning parental controls on and then setting up the Bitly website as a permanent exemption. The problem with that is that I publish books and design covers, that means a lot of photo sites that I use for work won't run as they also carry nude glamour photos. It's a real problem having to constantly turn stuff on and off to work.
