Probably an extremely common problem. How can i fix the 'ERR_SSL_VERSION_OR_CIPHER_MISMATCH' error

I have a API endpoint (api.domain.com) as a cloudflare worker custom-domain binding. DNS resolves to the proxied record; and the routes deliver the traffic to my worker. I can see the traffic in my workers log. However my client visiging https://api.domain.com/api/health (which is handled by js returning 200 when i test this offline).. fails with 'ERR_SSL_VERSION_OR_CIPHER_MISMATCH' 500 internal server error. I suspect this is something to do with the SSL/TLS Full vs Strict etc.. but no matter what setting I apply - i'm stuck. The odd thing is this was working this morning; and i don't know why it's no-longer working.
