    just added the line to the end of /etc/grafana/grafana.ini  file

    restarted per instrutions - still stalling. It was ending up with a specific "Grafana Server Error" message - that no longer is appearing. Now getting

    "login.OAuthLogin(state mismatch)"

    restarted plesk - nada

    updated to grafana 7.03, restarted grafana server - nada

    What is the fix on this please?
