I am sorry to hear you are having issues adding your bank account. I know this must be frustrating. It sounds like you may be experiencing an issue with our internal security system when trying to add your bank account.
I would suggest you clear your cache and cookies, or try again using an alternative browser. Sometimes the system just needs time to reset.
