It means you're trying to broadcast a transaction that conflicts with another transaction in your server's mempool.
Looks to me that you're trying to increase the fee from 0.00012 to 0.0002 without using RBF, is that correct? You can't do that without waiting for the first transaction to get dropped by the nodes.
Edit:
It appears the transaction you posted was included in a block that got orphaned.
Try switching servers manually and send again.
Same error do you have any idea to remove the double spend or do i need to wait more hours for the result of double spend.
Planning to increase the fee just to increase the chance to sent my transaction and i hope that the result of double spend transaction will be done soon..
Then just wait for it to be confirmed. You can always submit the transaction to
to make it faster.
BTW there's no double spend here. I don't know why bc.i is showing that message but that transaction doesn't have any conflicting transaction currently.
