When I use non-incognito browser to go to https://www.truist.com and enter a login and password that is valid I receive a JASON response message window that says {"type":"about:blank","title":"Bad Request","status":400,"detail":"Failed to convert 'userIdEncrypted' with value: ''","instance":"/dias/authenticate"} If I use a new private window I can login normally. Others have said the same thing but the suggested remedies do not work. I have delete all cach, cookies, and site data associated with the truist.com domain and the same problem happens. If I use Edge all works well with the truist.com site. Where does this useridEncrypted come from? Anyway, I thought I would try to clear out the userid which was prefilled in with the help of Firefox and just retype my id. Viola, everything worked. So wherever Firefox is retrieving the saved login id from, that must be corrupted somehow. Hope this will help somebody that is experiencing this problem.
