after upgrading of Grafana (from 6.5 to 7.0), everything works fine except logging in on Samsung Tizen 5.0 Smart TVs.
I’m able to open login page, even after entering login details I got “Logged in” notification, and in next moment I’m returned back to login screen without any notice.
Grafana log in /var/log/grafana does not have any errors shown, and neither do Nginix log. Have tried multiple smart TVs with no luck. Also cleared cache, cookies etc.
I’m using Nginx as reverse proxy, and haven’t got issues like this before.
