[HELP] Cannot login, error shows "BAD CSRF"

[sam (Sam Saffron)]

If you are running a reverse proxy 99.999% the issue is that you are not passing headers right to discourse.

Error 403 when trying to add articles or change any options

Holy moly, finally! I need to add a simple line to my nginx config: proxy_set_header X-Forwarded-Proto https; Who could guess that? So thank you and see you!
