Nextcloud - LetsEncrypt installation issues

Hi all,

I used the youtube guide from Technodad to get the installation up and going. Most things went in a breeze, easy to setup.
I did find a couple points that I had to change for my setup to run as intended:

Nextcloud.subdomain.conf <- Had to change this file to allow for bigger uploads and downloads
client_max_body_size 0;
location / {
include /config/nginx/proxy.conf;
resolver 127.0.0.11 valid=30s;
set $upstream_nextcloud nextcloud;
proxy_max_temp_file_size 2040m; made this proxy_max_temp_file_size 0;

proxy_pass https://$upstream_nextcloud:443;

With this setting in place the buffer file when sharing a link can get as big as needed. (keep in mind that this will 'grow' your docker image so you need enough space on the disk where docker runs or you need to map the tmp folder of the image to another drive)
This was actually the only thing I needed to change to get bigger files (movies, series, etc) to download.

I still have a problem though:
Whenever I transfer a big file from "SMB/CIFS A" to "SMB/CIFS B" I get a timeout in the android app or a could not move FILENAME when trying via Web interface.
The transfer does complete eventually though so most things seem to be working.

Any clue as to what I might have missed so I can fix this as well?

Kind regards,

For anybody having this issue and coming here for a fix, I managed to get it working eventually:

It turned out to be a fastCGI timeout in LetsEncrypt or Nextcloud, I am not really shure which one because I edited both nginx.conf files to allow for a bigger fastcgi timeout.

nginx.conf http section
http {

##
# Basic Settings
##

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 3600;
types_hash_max_size 2048;

# Timeout tryouts
#proxy_connect_timeout 600;
#proxy_send_timeout 600;
#proxy_read_timeout 600;
#send_timeout 600;
fastcgi_read_timeout 3600;
fastcgi_send_timeout 3600;
#fastcgi_connect_timeout 300;
#client_header_timeout 300;
#client_body_timeout 300;

I put the bold fastcgi settings in the conf file and the timeouts after 1 minute disappeared. Mabey there is a better way, I hope someone hovers over and can point it out to me. For me this seems to work at least.
