Why can't I connect after a Windows 10 update?

Normally, we recommend checking for any anti-virus/firewall blocking access to Splashtop servers. 

  1. Allow access to *.api.splashtop.com servers
  2. Allow access to *.relay.splashtop.com servers
  3. You can run a check tool, www.splashtop.com/check 
  4. Even if this passes, make sure non-ssl packets are allowed over port 443

Some customers have found that a Windows10 update, KB4056892, blocks Splashtop communications.  Please uninstall this KB update for now.
