The best way to get in is to make sure you click the moment the time/dialogue at the bottom right changes appropriately.

Not sure about everyone else, I used to follow the dialogue, but I recently realised that my dialogue comes up before the time changes, and when I click right after the dialogue, I don't get in since I clicked on it too soon. So I suggest you to follow the clock instead. D:

close the game (yes i mean quit not server select) reload the game

Not always necessary. I personally find just going to character select screen is enough to stop the lag.

seems the most reliable way to get in is to click when the "on schedule" turns to "recruited" since the dialogue comes to soon and the clock switches a second too late.
