How to fix it

  1. Raise sell slippage a little, or sell a smaller amount in steps.
  2. Raise the priority fee so the sell lands sooner.
  3. Retry with a fresh quote; in a fast dump each retry gets a lower price.

If that is not it

  • If every sell fails regardless of slippage, check whether the coin has graduated and now trades on PumpSwap.
