    Description

      Sometimes I have an "Diffie-Hellman parameters are not valid" when try to conect to SSL servers.

      Looking in qsslcontext_openssl.cpp i found than ssl_ctx_set_tmp_dh used also for all sockets, but at this manual page: http://linux.die.net/man/3/ssl_ctx_set_tmp_dh It states "These functions apply to SSL/TLS servers only."

      Look like we don't need to set DH params for client sockets?
