In case this can help someone out (my first post 
) :
Nextcloud server:
Nextcloud version: Nextcloud Hub 6 27.1.4
Operating system and version: Ubuntu 22.04.3 LTS
Apache version: 2.4.52
PHP version: 8.1.2-1ubuntu2.14
Nginx reverse-proxy server:
Operating system and version: Ubuntu 22.04.3 LTS
Nginx version:1.25.3
Context: Domain name proxied through cloudflared to my homelab. Ports 80 and 443 forwared to nginx reverse-proxy server. Nextcloud server hosted behind reverse-proxy.
The issue:
Taking pictures on my android phone everything uploads/syncs through the nextcloud app correctly only when I am on my home nextwork. When I am outside my home network (or when using VPN) I get the error message through my notifications: “Upload failed - Payload Too Large”
No error messages on nextcloud host, therefore error probably originates upstream of nextcloud/php server. Just to be safe and thorough I still opted to adjust php.ini as described. Nginx error logs ( /var/log/nginx/error.log):
client intended to send too large body: 2779819 bytes, client: x.x.x.x, server: youserver.domain, request: “PUT /remote.php/dav/files/…/475.jpg HTTP/1.1”, host: youdomain
Steps taken (thank you chatgpt):
On nextcloud host:
locate php.ini file ( /etc/php/8.1/cli/php.ini)
change the following directives (adjust to your needs):
upload_max_filesize = 128M
post_max_size = 128M
restart Apache
sudo service apache2 restart
or
sudo systemctl restart apache2
On nginx reverse-proxy server:
Open nextcloud config file. Location will depend on your configuration. Mine is located in /etc/nginx/conf.d/sites-available/nextcloud.conf
Under server block:
server {
# ... other configuration options
client_max_body_size 128M; # Adjust the value according to your needs
# ... other configuration options
Test nginx conf
sudo nginx -t
Restart nginx
sudo service nginx restart
Restart nextcloud app to force re-upload of the error-generated file.
Issue fixed; able to upload through VPN and when outside network. Also confirmed with empty log files on nginx server.
