    Description

      With Qt 5.8 Beta I get the following messages when using QSslSocket:

      qt.network.ssl: QSslSocket: cannot resolve SSL_set_alpn_protos
      qt.network.ssl: QSslSocket: cannot resolve SSL_CTX_set_alpn_select_cb
      qt.network.ssl: QSslSocket: cannot resolve SSL_get0_alpn_selected

      With Qt 5.7.0 there are no messages, so to me it looks like it's related to Qt 5.8.

      I am linking against OpenSSL 1.1.0b.

      I am not sure, if those error messages have a negative impact, because SSL seems to work. However, sometimes my application hangs immediately after startup (it's not responding). Unfortunately I cannot reproduce those problems reliably to debug it. As there are a few SSL requests performed immediately after startup, I thought that it might be related to those messages.
