Seen on mainnet

When the log line says fee_recipient.rs, the fee-recipient account the instruction passed as its second account was refused for that token. The client used a stale or generic recipient; Pump.fun accepts different recipients for some tokens. Rebuild the instruction with the recipient the Pump SDK reads from the global account for that mint; the amount and every other account are fine. TxWhy names the account passed and checks it against the protocol's current recipients.

Have the transaction that failed with this?
