Android Notes not able to login

Having trouble with logging in to hosted NextCloud with the Android Notes app. I have installed the NextCloud app, and have the Tasks app installed and running, along with calendar and contacts working, but have not been able to login to the Notes app. Receiving an ā€œInvalid login: URL/Server has errorsā€ message. Also have DAVx5 installed and using it for syncing the contacts, calendar, etc.
