TD bank connection

I cannot connect to my TD Bank account. I go through the process and put in the log in information, which I know is correct and it tells "that didnt work try signing in again" (103). But I know the user information is correct, I copied and pasted it directly from my online banking log in, I have tried several different browsers, and I even reached out to TD bank and was told that the issue was not on their end. Is there a way to put the bank information in manually, or to fix the connection?
