Hei. I am trying to use Ktor CIO client to make request to server that uses TLSv1.2 with ECDHE-RSA-AES256-GCM-SHA384 as cipher suite. But I get http handshake failure, if I use Apache as engine it works. I thought this was fixed here : https://github.com/ktorio/ktor/issues/439
Can someone help me please ?

Looks like Ktor CIO Jvm only supports cipher suites with max key strength 128 even though the list contains 256 strength…
