Possibly - and I'm guessing here ... there are no time slots? Maybe all players have been getting inbox messages about 'things happening' and a lot are on the move?
Yep. Pretty discouraging. I'm out in the black just trying to enjoy the game and lately it's been ~40 minute jump wait times and now this "no time slot" nonsense.
Yeah to many jumps queued up, there is a limit to the number they can run in a given amount of time and it appears we have hit that limit and they don't want to start giving players jump times in the hours plus.
