Curl fails when connecting to server that does not accept TLSv1.1 or TLSv1.2 handshakes. This occurs even if the "--tlsv1.0" or "--tlsv1.1" options to the curl command are used.
Curl will fail.
Curl is used to attempt to connect to a server that does not understand TLSv1.1 and/or TLSv1.2 handshakes. This occurs when using software v11.5.4 HF2 through 11.5.6 or v11.6.1 HF1 through 11.6.3.
Use "curl-apd" rather than "curl". curl-apd does not currently implement TLSv1.1 or TLSv1.2.
Curl now honors the tlsv version flag, so the system correctly uses TLSv1.0, TLSv1.1, or TLSv1.2, as specified.
