The league has ended???

I have a character in Breach league, but since now I can't access it.
When i press Play it shows abnormal disconnection the league has ended

What does it mean. Can't i keep my current progress and the character to normal league

Yes the League has ended.
Wait a few minutes to a few hours and your characters and your stash will be transferred to the Standard league (permanent league). It's just unlucky timing that you just started a character the day the league ends.
The new league will start Friday and it looks pretty promising. I suggest starting a new character there once it starts.

I would take off that picture if I was you as it shows your login info.

Oh, i havent though about it. Thank you for the info!
