I've had this issue for as long as I can remember. I'm currently playing through Living World Season 2, and I cannot complete Hidden Arcana. I have disconnected at two cutscenes within Glint's Lair - the one after defeating the Malevolent Memory, and at the memory cutscene after defeating the Distorted Facet of Light. This is rather problematic and takes all sense of fun out of the game. I really enjoyed the Malevolent Memory encounter, but the thought of having to do it again in order to progress is grueling. I've tried numerous things in this thread - camera settings, firewall settings, antivirus - everything short of using a VPN, because I feel like that shouldn't be expected of me to get my game working, and would degrade gameplay quality even further. Technical details that might matter include several ISPs, Windows 7 and Windows 10, antivirus and firewalls disabled (even though they're most likely not the culprits), running in compatibility mode, running as administrator, and various builds from an AMD Athlon with an ATI (remember them?) HD 6770 to a i7 7700k and GTX 980s.
