Connection to server timed out (code:leaf)

Had same problem. Currently solved by going directly into C:/Program Files(x86)/Origin Games/Apex and running r5apex.exe as admin. 

I have similar issues but I'm still able to play (with some patience).

Perhaps it might work for some of you, so I'll share my process:

1) I log in to Apex Legends and I get stuck on the black loading screen for a while. Sometimes I get through the first time, sometimes I need a second try.

2) When in the lobby, I change the game mode to "firing range". This will freeze my game and it makes my computer sound like it wants to mow my lawn. I get the unable to connect notification (code:net).

3) I re-enter the lobby and right now, the game mode is already the firing range. I select "ready" and there are no issues now.

4) After a few minutes of killing motionless and defenseless dummies, I quit the firing range and go back to the lobby.

5) I select a public match (trios). My game will stutter once but it doesn't kick me out. I select "ready" and it puts me in a game with some delay but it's still less than a minute.

As you can see, this is NOT a fix. However, it allows me to play the game and my games feel no different than before the latest update.

i keep getting Code Wheel
