Greetings,

My new piwigo install is working fine except for two uploading-problems.
Could they be related? And how to solve?

1.
When I try to upload one or more files as admin using admin.php?page=photos_add
I get the error “HTTP-error” showing in a yellow triangle right from the uploading file.
The message below stalls at “0/5 files uploaded 94% 19 mb” but after a few minutes the pictures do appear in the chosen album.

nginx/error.log: 2022/05/27 12:55:44 [error] 383#383: *552 upstream timed out (110: Operation timed out) while reading response header from upstream, client: 172.31.0.2, server: _, request: "POST /ws.php?method=pwg.images.upload&format=json HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "dagvandenatuurfotografie.nl", referrer: "https://dagvandenatuurfotografie.nl/admin.php?page=photos_add&album=1"

I followed jameswyper’s advice at post: 182593
and added the following code to my reverse proxy’s nginx.tmpl file

proxy_set_header X-Forwarded-Host $host;

and added the following code to my piwigo’s nginx/site-confs/default file

fastcgi_param HTTPS 'on';

without succes.


2.
When I try to upload file(s) as admin or test-user, using the community plugin
the progress bar doesn’t move at all and the button “Cancel” is not clickable. The page stays in this state and the file is never uploaded.

community plugin configuration:
every registered user         Album1     high trust, 5 photo's, 50MB

php/error.log: [27-May-2022 15:02:40] WARNING: [pool www] server reached pm.max_children setting (5), consider raising it
[27-May-2022 15:16:10] NOTICE: fpm is running, pid 361
[27-May-2022 15:16:10] NOTICE: ready to handle connections

I raised  pm.max_children from 5 to 20 in the file /etc/php7/php-fpm.d/www.conf without succes.

Installation: I installed this piwigo with docker using mariadb:latest and lscr.io/linuxserver/piwigo
It interacts with network "proxy-tier": using jwilder/nginx-proxy as a reverse proxy and jrcs/letsencrypt-nginx-proxy-companion for SSL-certificates.
