why my txid can't broadcast another bitcoin-abc node?

In bitcoin-abc 0.18.5, I have a txid in the local mempool. Unable to broadcast to other nodes (and certainly not to block chains), I did the following checks:

1. All input utxo is unspent

2. The fee is enough, call by RPC "bitcoin-cli estimatefee 6"

3. Check the. bitcoin / debug. log and find some log: relaying WTX "4ca984b786cbe2168d36f9e581e3ec5a9b2afa99ac80e0f502ae36f53a7bd0".

The problem is:
Why is this TX not broadcasted to MemPool on other nodes?
