Hi everyone. I send a transaction to testnet using tonsdk and this is the result:

{'ok': True, 'result': {'@type': 'raw.extMessageInfo', 'hash': 'TQlo5aoQgdNMTxnbjJs2Q7cpRajB5Q4B/+mv/fHpiEw=', '@extra': '1684660836.6978266:4:0.5563136092008995'}}

And fee is paid.
But the transaction does not happen in chain. I don't see the transaction and it does not appear in the wallet transactions.
Today it happens.
It was work two days ago. What is wrong?
