Settings / add account /e/

I managed (happily) to install /e OS on Lenovo P2a42. Upon starting I entered my /e/ account info and it seemed to sync; then I continued to use and adapt to purpose over next few days. Then my /e account stopped syncing. I re-entered account info and it continues to say wrong credentials …but it’s not. I need troubleshooting help. Would changing security settings in my web account affect this? Thanks
