lxc with nextcloud and nginx proxy: Unknown: POST Content-Length - php

Question

I have two lxc containers. One is the proxy with nginx and this config:
server {
server_name cloud.malte-kiefer.de;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://cloud.lxd;
}
real_ip_header proxy_protocol;
set_real_ip_from 127.0.0.1;
listen [::]:443 ssl http2 proxy_protocol;
listen 443 ssl http2 proxy_protocol;
ssl_certificate /etc/nginx/ssl/cloud.malte-kiefer.de/fullchain.cer;
ssl_certificate_key /etc/nginx/ssl/cloud.malte-kiefer.de/privkey.key;
}
server {
listen 80 proxy_protocol;
listen [::]:80 proxy_protocol;
server_name cloud.malte-kiefer.de;
location / {
return 301 https://cloud.malte-kiefer.de$request_uri;
}
return 404;
}
Then I have the cloud container with nextcloud with this config:
upstream php-handler {
server unix:/var/run/php/php7.3-fpm.sock;
}
server {
listen 80 default_server;
listen [::]:80 default_server;

}
When I try to open the URL I see the installation page from nextcloud. When I enter information and send it reload from page and this in the nextcloud log:
Unknown: POST Content-Length of 213 bytes exceeds the limit of 16
bytes at Unknown#0
This is the nginx log from the nextcloud container
2020/01/13 17:32:20 [error] 416#416: *8 FastCGI sent in stderr: "PHP
message: PHP Warning: Unknown: POST Content-Length of 213 bytes
exceeds the limit of 16 bytes in Unknown on line 0" while reading
response header from upstream, client: 89.204.135.199, server:
cloud.malte-kiefer.de, request: "POST /index.php HTTP/1.0", upstream:
"fastcgi://unix:/var/run/php/php7.3-fpm.sock:", host:
"cloud.malte-kiefer.de"
I check my PHP ini file:
root#cloud:~# grep -R "post_max_size" /etc/php/
/etc/php/7.3/fpm/php.ini:post_max_size = 16GB
/etc/php/7.3/cli/php.ini:post_max_size = 16GB
/etc/php/7.3/phpdbg/php.ini:post_max_size = 8M
root#cloud:~# grep -R "memory_limit" /etc/php/
/etc/php/7.3/fpm/pool.d/www.conf:;php_admin_value[memory_limit] = 32M
/etc/php/7.3/fpm/php.ini:memory_limit = 512M
/etc/php/7.3/cli/php.ini:memory_limit = 512M
/etc/php/7.3/phpdbg/php.ini:memory_limit = 128M
I can't find the issue. Maybe you guys can help me.

Answer 1

Ok, it was a missconfig in the php.ini file.
I totally removed PHP vom the nextcloud container, reinstalled and it works now.
