DISCOURSE_FORCE_HTTPS가 ‘false’로 설정되어 로그인 대화상자에 로고 링크가 없습니다

Yes, you are quite right, thanks @JammyDodger

Turns out my app.yml had the DISCOURSE_FORCE_HTTPS setting set to ‘false’

After changing it to ‘true’ & rebuilding, the logo reappears, and the warning in the administrator dashboard dissapeared.
