Hey everyone !
I’m having a hard time configuring my reverse proxy. I followed the official guide and look at some other configuration on StackOverflow but none of them work. Right now when i try to reach cloud.domain.tld, it redirect me to the default Nginx page with the adresshttps://cloud.domain.tld//, with two backslash at the end.
I’m looking at it for too long now and i’m sure it’s pretty obvious… Thanks to anyone who takes the time to read this 
My config files :
/etc/nginx/conf.d/nextcloud.conf :
server {
server_name cloud.domain.tld;
client_max_body_size 0;
underscores_in_headers on;
location /nextcloud {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
add_header Front-End-Https on;
proxy_headers_hash_max_size 512;
proxy_headers_hash_bucket_size 64;
proxy_buffering off;
proxy_redirect off;
proxy_max_temp_file_size 0;
proxy_pass http://192.168.0.42;
}
