The issue you are facing:
After installing Nextcloud docker apache instance I want to configure external nginx proxy on host to route to nextcloud docker.
Nextcloud in docker is running fine on port 8088 (unencrypted). Nginx conf is like follows:
server {
listen 80 http2;
listen [::]:80 http2;
#i have the correct domain on the configs
server_name test.floeser.org;
root /var/www/html;
index index.php index.html /index.php$request_uri;
location / {
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;
proxy_pass http://127.0.0.1:8088/;
proxy_read_timeout 36000s;
client_max_body_size 0;
}
}
Trying to access the Nextcloud docker will result in downloading a file and not showing up Nextcloud page.
Is this the first time you’ve seen this error? (Y/N):
