Issues with secure SPDY

  • I used to connect to a server via HTTPS without problems. Now the server admin must have changed the configuration to try to speed up transfer to Chrome based browsers by enabling the SPDY protocol, but since then Vivaldi cannot connect anymore due to the error: ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY Which hints could I give the site admin to fix mistakes in this area? And in the meantime, if I had to disable SPDY in Vivaldi, how would I do that? I bet it is hidden very secretly in some advanced options for which you have to know the special URL exactly...

  • LigH,

    You can use a Command Line switch in the Vivaldi startup shortcut:

    The fascinating Chrome net-internals page will capture traffic before and after you use the switch:
