custom program error: 0x178c

What it means

Exceeded max fee rate

What to do

Reduce the amount — a protocol limit or cap applies.

Have the transaction that failed with this?

Paste its signature. TxWhy shows the exact instruction and inner call that raised the error, and rebuilds the transaction when the cause is one it can fix (compute limit, expired blockhash, priority fee, stale swap quote).

Code 6028 means something else in other programs

Custom codes are private to each program. Check which program actually raised it: it is the innermost failed call, not necessarily the program you called.
