Hi community,
This is an informative post more than a question. I have been having issues with parental controls not blocking adult websites including those with obvious related words in their names, (e.g. p***hub.com) and EE have been investigating for a number of weeks now.
They have provided a workaround while they are looking for a proper fix, but essentially it comes down to newer versions of browsers like Edge or Chrome having a new experimental feature called TLS 1.3 hybridized Kyber support enabled which breaks the parental controls feature. My loose understanding is that this is because the feature uses a new type of cryptographic algorithm in the browser session that makes it more private and instead of getting the EE banner *Access to this website has been blocked* page, the browser will display its own inbuilt "The connection for this site is not secure" page because EE's parental control systems can't intercept it properly. However, with TLS 1.3 hybridized Kyber support enabled (which it is by default in the latest browser updates) the user can hit the refresh button repeatedly until the browser complies and loads the site that should be blocked.
I am putting EE's workaround here as I understand it is not just my account that is affected, but likely anybody using this the parental controls may be affected. The current workaround is to disable this experimental browser feature as follows:
1. In your browser, type or paste the following setting URL into the address bar and hit enter: chrome://flags/#enable-tls13-kyber
2. Change the TLS 1.3 hybridized Kyber support flag to *Disabled*.
3. Close and re-open the browser.
Best of luck.
