We are having some very strange results reported for one of our sites. We have tested another of our sites and this works fine. The sites have exactly the same SSL config and we can't figure out why we are having issues.
This is the problem server with strange results:
This is an example of a working result:
The main issue is the handshake simulation. As you can see, we are getting lots of "Protocol or cipher suite mismatch". Also, the cipher detection shows, "we could not determine if the server has a preference" - when the server DOES specify this.
Also, the test for the working result runs much faster than the test for the problem result.
The example of the working results above uses the exact same nginx server, with the exact same SSL/cipher config server albeit on a different IP address.
I can't figure this out - the configs for both sites are exactly the same.
We also keep getting, "Assessment failed: Unexpected failure"
Can anyone shed any light?
