The most common protocol mismatch that causes this is speaking HTTPS to an HTTP port. For instance, you can see this error at normal times with URLs like https://google.com:80/ https://example.com:80/ If you get some misconfiguration where port 443 is speaking HTTP instead of HTTPS, you'll see the same error.
