So finally, I found a solution ! 🤩 I checked my nextcloud.subdomain.conf and added/removed everything so both files were similar.   In case someone has the same issue, here's my onlyoffice.subdomain.conf file with added/removed comments # only office doc server server { listen 443 ssl; ## Added listen [::]:443 ssl; server_name office.*; include /config/nginx/ssl.conf; ## Added add_header Strict-Transport-Security "max-age=15768000; includeSubDoma
