Any idea why I can't connect to a certain website?

Been trying to access www.radio-on.co.uk (it's a record shop in Bristol) but when I try (through Chrome) it says "this site can't be reached". When I run the Windows Network Diagnostics, it just advises me to put www at the front, which I do to no avail. Not massively arsed, more perplexed.

Gives me a https security warning. I'd guess some kind of certificate has expired on their end, but I'm no expert.

Loads okay for me, cert is good (TLS 1.3, Let's Encrypt, 2 Oct -> 32 Dec). Maybe if it was a stale certificate hanging around a hard <ctrl>+<shift>+r reload might fix it up.

Warns me the connection's not private. Expired certificate sounds about right

Are they on Twitter?

Actually look at the certificate. It is valid as far as I can see.
