Oh ok … Of course I’m on my server in ssh, but I don’t know the Rails console. Thank you to help us to debug this …
My CloudFlare SSL is in “Flexible” mode. Maybe show I try in “Strict” mode ? But in this case I have to do it at night cause we have big traffic actually on this domain, and that could take several hours to change the cloudflare certificate … And I probably should change my nginx configs.
