Unfortunately, this is a fairly new routing number, and not all institutions’ software update their list of routing numbers regularly. This is resulting in the error you are seeing. You can ask your financial institutions to verify the routing number via the link below and to update their list of routing numbers. If you need to transfer funds before then, you can look into other transfer options such as a wire transfer, which can be sent to your new account, and the new routing number will work just fine for that!
Here is a link below which verifies our new account as having an active routing number with the Federal Reserve. This may be useful when talking to your respective institution.
