use a protocol on your website that is properly supported.
In all versions of Google Chrome I am now advised;
This site can’t provide a secure connection
haveibeenpwned.com uses an unsupported protocol.
ERRSSLVERSIONORCIPHER_MISMATCH
The client and server don't support a common SSL protocol version or cipher suite. This is likely to be caused when the server needs RC4, which is no longer considered secure.
So, why can't you use a proper protocol?

I’m as close to certain as possible that this is a problem at your end, there’s been a heap of traffic through the site today and yours is the only mention of this. TLS termination is done at Cloudflare and nothing has changed configuration wise.
