Electronic Bank Wire

For some reason every single time I try to transfer funds from my bank acct. Into fidelity I get a "we're sorry we're unable to complete your request response."

I have been trying for at least the past few months. The furthest I have got was last Friday when I was finally able to sign into my bank to make a request with Finicity (a separate company that processes electronic wire transfers) and right after I received this message.

I'd rather not have to mail in private bank info t fidelity's headquarters (I mean I could drive to the nearest one to drop it off in person).

What seems to be the issue here?
