The transaction failed when online banking remitted money across banks. Why is the response code EBBAG0 1 1?

Is your online bank registered with other banks? Some banks do not provide the function of being withdrawn. Prompt as soon as you operate: response code: EBBAG0 1 1, response information: the bank has refused. For reference only, I don't know how you operate it.

For example:

Remittance includes two steps at the database level. For example, you remitted 100 yuan to your girlfriend.

First, your account balance in the database is less 100 yuan, and then your girlfriend's account is more 100 yuan. These two steps are an atom and a basic inseparable unit. If your account is short of 100 yuan, it will trigger a debit message, and then because of power failure or other network reasons.

You didn't add 100 yuan to your girlfriend's account, so database-level rollback is rollback. The money in your account has naturally recovered, but the debit message has been sent out.

As for the transfer from Huaxia Bank to China Bank, it will go through Huaxia Bank's core bank, cnaps front-end machine, China People's Bank's cnaps front-end machine, China Bank's cnaps front-end machine and China Bank's core bank. I think any problems at the database level, including physical, timeout, network and other anomalies, will be thrown to ensure the atomicity of transactions.
