ACH deposit to fund new account

Why is my ACH request to fund my account getting cancelled? I have confirmed that there is money in the account?

Update: I have got an email stating the obvious that transfer was cancelled by Plaid. No reason why or what my next steps should be. I initiated another transaction which also failed. No doubt i will get the email again. However, no contact from the company. Make me nervous sending real money. I have ran a paper algorithm since March '20 and I want to not run it on real money. Very disappointed.
