Once a browser has seen an HSTS flag it will never attempt a non-TLS connection to that site (unless it successfully makes a TLS connection and the flag is gone).
This error is caused by a bad certificate. It can show up if your certificate expired, for instance. It's confusing that the HSTS error takes precedence, I think the bad certificate should take precedence but there you have it.
My money is on the hospital trying to use TLS stripping.
