I tried on launch night, here in Lancashire, England on my laptop, from 7pm - 1030pm, when I finally gave up. The best I got from at least 30 attempts to log into the game was two views from my cockpit, then hit SC, then stuck there until I tasked out of the game.
(BTW, the ISSUES DETECTED message on the launcher has been showing since this update hit & Iv never seen it any different).
I tried again on Wednesday morning & got on without any issues. I then had a good session from around 1200hrs - 2000hrs, no connection issues at all, until 2000hrs.
I was out exploring then was noticing names on my friends list going offline one by one quite quickly, I was jumping to another system, saying to my wife 'Oh dear, my friends are getting kicked, I think I'm next, then BAMM!...gone.
Maybe that's it! if I delete my friends on the list, then it'll let me play.......but then I'll have no friends to play with!!
I only tried a couple times then to log back in, I really wasn't gonna spend another 3 hours ing around trying to get into the game like Tuesday night, so I logged off.
Looks like the game's only suitable to play in the UK, when the rest of the player base is working or sleeping. Glad my forced early retirement payed off!
