Custom Challenges

Failing to get a game with the parameters I set for a Custom Challenge, I set a different range.  But, at some point, I got a message, "challenge failed.  You cannot set a new challenge with the same parameters."  For how long does this restriction apply?; the rest of the day?; forever?

I see you play 60 min games which are probably not easy to seek.

Maybe try 15|10, 30 min, or 45|45.

thx.  a f/u question.  I set a Custom Challenge with a range of -50 to +50.  Noone responded so I changed it to -50 to +100.  I got a messsage, "challenge failed.  you cannot set a challenge with the same parameters."  But, of course, these aren't the same parameters.  Pls explain.

You should ask chess.com support that question:

To minimize seeks times, don’t make the opponent’s rating range too narrow. My opinion: opponents rated 100 points below your rating will play competitive games.
