My setup:
All services run on my raspberry pi, started with docker-compose (given with used images)
Nextcloud 20.0.2 - nextcloud:latest
nginx - alexanderkrause/rpi-nginx-proxy:latest
letsencrypt - alexanderkrause/rpi-letsencrypt-nginx-proxy-companion:latest
MariaDB - jsurf/rpi-mariadb:latest
The issue you are facing:
I want to upload a file with 4.4 GB (over web interface or windows client - does not matter) and the upload goes through. At the end I get the error “Error when assembling chunks. Status code 504”. When I upload the file with the windows client a file gets created in nextcloud, but it is a little bigger than 400MB and not the total 4.4 GB.
Is this the first time you’ve seen this error?
Yes, but I never uploaded such a big file before.
The output of your Nextcloud log in Admin > Logging:
I can not find a directly related log entry. Same story with “docker logs nextcloud”. In Admin > Logging I fond the following:

What I already tried:
- nginx container - /etc/nginx/nginx.conf
added the following lines in http segment:
client_max_body_size 0;
fastcgi_connect_timeout 60;
fastcgi_send_timeout 1800;
fastcgi_read_timeout 1800;
- nextcloud container - added file in /usr/local/etc/php/conf.d/tweak.ini with content:
request_terminate_timeout=3600
post_max_size = 100G
upload_max_filesize = 100G
max_execution_time=3600
No success…
I really hope someone can help me here! 
Thanks in advance!

I have the same behaviour, same settings. Try everythings, but nothing achieved. Hope someone could help us!

I have a solution, but maybe not in a way you expected.
My nextcloud docker container is now on version 20.0.4. Recently I switched from nginx to traefik v2. Now the upload went through and everything works. My nextcloud container still has the settings mentioned above.
So if you want to keep your nginx I think you have to search for the problem there. Good luck!
If you could point me to a proper tutorial for switching to Traefik v2, because I’m a bit lost 
I don’t know any good tutorial, because I knew traefik from work. But here are a few hints:
I use the official traefik 2 docker image. Put traefik and nextcloud in the same docker network. Now use traefik with these commands and these labels:
command:
- "--providers.docker=true"
- "--providers.docker.exposedbydefault=false"
- "--entrypoints.web.address=:80"
- "--entrypoints.web.http.middlewares=redirect-to-https@docker" # use middleware defined in labels. Always redirect http to https
- "--entrypoints.websecure.address=:443"
- "--serverstransport.insecureskipverify=true"
- "--certificatesresolvers.letsencrypt.acme.email=your@mail.com"
- "--certificatesresolvers.letsencrypt.acme.storage=acme.json"
- "--certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=web"
# - "--certificatesresolvers.letsencrypt.acme.caserver=https://acme-staging-v02.api.letsencrypt.org/directory" use this for testing. Letsencrypt as a ratio limit on its production endpoint
# - "--log.level=DEBUG"
# - "--accesslog=true" help with finding errors
labels:
- "traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"
- "traefik.http.middlewares.redirect-to-https.redirectscheme.permanent=true"
and now you add these labels to your nextcloud container:
labels:
- "traefik.http.middlewares.nextcloud_headers.headers.stsSeconds=315360000" # for security mentioned in server overview
- "traefik.http.middlewares.calcarddav.redirectregex.permanent=true"
- "traefik.http.middlewares.calcarddav.redirectregex.regex=https://(.*)/.well-known/(card|cal)dav"
- "traefik.http.middlewares.calcarddav.redirectregex.replacement=https://$$1/remote.php/dav/" # important fĂĽr caldav and carddav
- "traefik.enable=true"
- "traefik.http.routers.nextcloud_http.rule=Host(`example.com`)"
- "traefik.http.routers.nextcloud_http.entrypoints=web"
- "traefik.http.routers.nextcloud_https.rule=Host(`example.com`)"
- "traefik.http.routers.nextcloud_https.entrypoints=websecure"
- "traefik.http.routers.nextcloud_https.middlewares=calcarddav,nextcloud_headers"
- "traefik.http.routers.nextcloud_https.tls=true"
- "traefik.http.routers.nextcloud_https.tls.certresolver=letsencrypt" # defined in traefik command
The traefik documentation is pretty good. Just remeber that everything defined in traefiks command area is its static configuration and all labels are a dynamic configuration. This fact caused me confusion many times 
Good luck!

I’m just putting this here for people in the future who may be having this issue. Although I’m not using a plain ngnix docker container as my reverse proxy, I am using the Nginx Proxy Manager container to do all of my reverse proxy needs. I’ve been working on this for days trying to figure it out and tried all of the same things everyone else has tried until I saw a post on an Unraid forum. Adding these lines to the proxy config for Nextcloud fixed my issue
proxy_connect_timeout 1d;
proxy_send_timeout 1d;
proxy_read_timeout 1d;
send_timeout 1d;
Basically all this does is increase the timeouts on the nginx side to 1 day instead of whatever the default may be. Obviously this is probably way more than it needs to be, but it fixed my problem.
edit: Also just for clarification, this was in addition to the lines listed in the original post.

Just to second it, these lines fixed the issue for me as well.
Hey I have a similar situation as you, also behind NPM in a container, do you happen to know which proxy config file I’m supposed to look for? I’ve added those lines to the file in /data/compose/6/data/nginx/proxy_host/4.conf (which corresponded to the domain that is forwarded to the nextcloud container on the same network), but it doesn’t seem to work
I just created an account to say thank you, it worked for me (y)
Thank you very much for this solution.
