This is what I am currently doing to log into Destiny on my PS4 since I started receiving the Cannot Connect to Servers message. This solution has been posted in the past by other users. Turn your phone into a hotspot. I have an iPhone and this was simple to do. Connect your PS4 through your hotspot. Log into Destiny and be in orbit. Go to your PS4 network settings and switch to your normal LAN/WiFi settings. This will disconnect you from the servers, but should allow you to reconnect.
