Hello,
I use on my server:
linuxserver / piwigo
linuxserver / swag
ghcr.io/linuxserver/nextcloud
I did not touch the initial configuration and it works. Only the day before yesterday, I wanted to download a finier on PIWIGO of 300 MB or more and impossible I found this error in the logs of the swag container and in that of the piwigo container:
upstream prematurely closed connection while reading upstream, client: xx.xxx.xxx.xxx, server: photos. *, request: “GET /action.php?id=5496&part=e&download HTTP / 2.0”, upstream: "http://172.20.0.4: 80 / action.php? Id = 5496 & part = e & download "
While researching, I saw that it was necessary to play on the values of:
client_body_buffer_size
client_header_buffer_size
client_max_body_size
large_client_header_buffers
Being a new one in the Nginx configuration I am not out of it. can you help me find the correct configuration please?
