I configured a private Stellar blockchain network composed of 2 nodes. When I try to create an account on this private blockchain I get the following error:
stellar_sdk.exceptions.BadRequestError: {
"type": "https://stellar.org/horizon-errors/transaction_failed",
"title": "Transaction Failed",
"status": 400,
"detail": "The transaction failed when submitted to the stellar network. The `extras.result_codes` field on this response contains further details. Descriptions of each code can be found at: https://developers.stellar.org/api/errors/http-status-codes/horizon-specific/transaction-failed/",

"result_codes": {
"transaction": "tx_not_supported"
},
"result_xdr": "AAAAAAAAAGT////0AAAAAA=="
}
I'm unable to figure out which is the problem. To create an account I used the following python program:
from stellar_sdk import Keypair, Network, Server, TransactionBuilder
server = Server(horizon_url="http://192.168.184.62:8000")
#### destination address
destination = Keypair.random()
print(destination.secret)
print(destination.public_key)
#### root secret
source = Keypair.from_secret("SBZ2E3NQE4ZEN3GAR2WZNYKYEXB37CZXPZYO7WKPQ2KPSLYNVB6VNI5B")
source_account = server.load_account(account_id=source.public_key)
transaction = (
TransactionBuilder(
source_account=source_account,
network_passphrase="Private Network ; February 2022",
base_fee=100,
)
.append_create_account_op(
destination=destination.public_key, starting_balance="12.25"
)
.set_timeout(30)
.build()
)
transaction.sign(source)
response = server.submit_transaction(transaction)
print(f"Transaction hash: {response['hash']}")
print(
f"New Keypair: \n\taccount id: {destination.public_key}\n\tsecret seed: {destination.secret}"
)
The 2 stellar core instances are configured like the following one of the first node:
