'The Connection For This Site Is Not Secure'

[SteveP29]

Is the message if I try to view the site on the desktop or over WiFi on my phone (turn the WiFi off and it works perfectly, hence my ability to post this)

I've noticed it with some sites that I access this weekend. They also work perfectly on mobile data.
Googling tends to suggest I clear cache and cookies and that the site(s) I'm trying to access have no SSL certificate.

I reckon it's pretty coincidental that this is only happening on WiFi and not while I use mobile data on my phone.

Is this a me (as in my WiFi) or them issue?
Anyone got any ideas?

Do you have any sort of parental controls enabled on your router? That’s the kind of error you get where something is trying to intercept the connection.

Have you tried a different browser on the affected sites?

Not that I'm aware of, as far as I know, it is still in factory condition, ievno changes made or passphrase changed

Have you tried a different browser on the affected sites?

All but one of the affected sites loads up on Chrome, so I must presume this is mostly an Edge issue.
I forgot to quantify, I use Edge.

Definitely a local issue.

As @JamesT said, it's almost certain that there's something acting as a man-in-the-middle (MitM) - typical and most likely culprits would be some kind of traffic inspection facility in the router or ISP network or web protection/anti-virus software on the device. Do you experience anything similar on sites that implement HSTS such as Facebook.com?

I have no problem getting onto Facebook either on the computer or mobile via WiFi.

I've just tried to get onto the router via 182.168 etc and I get the message 'this site can't be reached, I will have investigate that later.

I have the same antivirus program running on the computer and the mobile, but that doesn't explain how I can get onto sites via Chrome on the computer where Edge gives me the error.

Rather confusing as the sites that I now can't access are sites I browse regularly, this site being one of them.

I have found the problem occasionally if using private browsing. The workaround is to type the whole url including the "https://"

This is usually caused by connecting via a public WiFi network which presents a login screen. You try to connect to e.g. Https://BBC.co.uk and you get an insecure response from e.g http://joeblogswifi.co.uk. Your browser will report there is an error and the connection is insecure.

In order to register on the WiFi hotspot you have to temporarily allow an insecure connection.

This will then present an insecure http page with a click box asking that you accept the Ts&Cs to connect to the internet. You may be asked to enter a name and email address in some of sites.

There is a legal requirement for public WiFi hotspots to collect some info on who is connected and when.

Once you're properly connected to the WiFi hotspot then you can surf securely using https. The WiFi hotspot can't read the secure traffic although they might block access to some sites.

Do you have a work VPN connected?

Tried that after I read your post, no success here unfortunately

Its the WiFi at home that's doing it

Do you have a work VPN connected?

I don't use a VPN at home and we don't have one on our work WiFi

Who is your ISP? Does it affect all devices using your home connection or just one/some?

Just to be clear, it's a problem with your set up - not a problem with the websites you're trying to connect to. It's probably fairly easy to work around, but something definitely odd has happened as it's not something you would expect on a normal home internet connection.

We're with EE

I'm having the problem on my mobile and on my desktop computer when connected to our WiFi
I've not asked anyone else in our house to try anything, I don't want to involve my o/h as she once bricked her mobile phone when she messed around with her settings so many times after her phone kept telling her she was in London or Brighton, rather than just turning on her location services, I shudder to think what could happen if she starts messing with the router and network settings

I did imagine it would be a problem on our WiFi, as I can access all those sites that I can't access at home when I'm at work, or when using mobile data on my phone

I would double-check whether the controls have got turned on - https://ee.co.uk/help/broadband/getting-started/web-protect
It's not unknown for ISPs to remotely update your router and end up resetting things back to defaults.
The other troubleshooting method I would try is to change the DNS settings on a device you're using to use an alternative provider such as 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) and see if the problem goes away. If it does that would point more conclusively that it's EE doing something.
