Very annoying - been trying on and off for about 8 hours now with no joy. Tried on a laptop with Win 7 as opposed to Win 10, and with a different antivirus - exact same issue.
The game was played on both machines 2 weeks ago with zero problems. The laptop hasn't been booted up since Trove was last played so no changes to that machine. The only difference is the latest patch which refuses to download.
Searching on-line it seems that this bug has plagued Trion at different times for a couple of years and different games. And I couldn't find a resolution on any of the threads I found. Just to reiterate what I mentioned earlier, I updated Rift and played that game today; I updated Devilian and played that game today; and I updated Archeage - all with no issues and after this bug with Trove. So it's not hatred from my ISP to Trion.
Just in case any devs are interested, the following lines are at the end of the Glyph log file in Appdata/Local/Glyph/

I've tried browsing directly to that URL and can get there via the browser - it's just the patcher that refuses to connect to that location. Oh and I'm running everything I can think of in Glyph and Trove with admin rights, and it's all been allowed through the antivirus and firewall.
Edit: I managed to get into the game but it wasn't easy. UPDATE initially, clicked it to be told that my game was already up to date; clicked PLAY, got 1016, clicked PLAY again and got in. But it's touch and go. Tried again - UPDATE -> 1016 -> UPDATE -> 1016 -> UPDATE->1016-> PLAY->1016...and so on; several PLAY->1016's later I get the initialising bar; then it mixes between UPDATE->1016 and PLAY->1016 with the bar going nowhere. I know it works because I was in the game 30 minutes ago! Giving up again - I'll try it tomorrow. Might work on a weekday...
