Problem solved Thank you everyone who responded. I have tried everything I could think of, and when nothing worked, I decided to go over the setup, line by line, word by word and that's when I found it! It was a typo in configuration of my nginx, i.e., my own mistake. The following entries were wrong: proxy_set_header X-Forward-For ... proxy_set_header X-Forward-Proto ... They should be X-Forwarded-For and X-Forwarded-Proto, notice they were missing ed in the word forward !
