Opened: Feb 05, 2018

Severity: 3-Major


The SSL filter will not always add the ALPN extension.


The failure to add the ALPN extension may result in the failure to negotiate the proper protocol.


If the negotiated cipher is not HTTP/2 compliant, the SSL filter may not add the ALPN extension.


There is no workaround at this time.
