Grafana 401 Error - suggestions not working

I have read the many posts on this but just can’t get it right. For anyone but the system admin user, viewing a shared grafana link give a 401 error.

My config is as below. While many posts say SSL should be disabled, there are a number that say it does not need to be. Also when I remove SSL and specify the custom port, Home Assistant returns “Unable to load iframes pointing at websites using http: if Home Assistant is served over https:.”

(I am using a standalone NginX Proxy Manager for Home Assistant access).
