Server info :
Nextcloud Server : 24.0.6
Operating system and version : Buster on Raspberry Pi 4
Apache : Server version: Apache/2.4.38 (Raspbian)
PHP version : 8.0.26
Clients info:
Windows 10 with client 3.5.4 or 3.7.3
Ubuntu Ubuntu 20.04.5 LTS with clients 3.5.4 or Nextcloud-3.7.3-x86_64.AppImage
Clients access the server by IP address 192.168.2.4 when they are on the LAN or by my public hostname when they are on the internet.
For the access by IP address a self signed certificate is in use and for the access by public hostname I use a Let’s Encrypt certificate.
The clients on my LAN are connected to a 100Mb switch and I have a 100 Mb internet connection.
The issue I am facing:
I am facing the issue below when I run more than 1 client but also with 1 client up only.
The clients can upload large files like 9 GB without any issue but can not download them.
Downloads start but fail after some GB.
Red Cross in Nexcloud Settings screen with message ‘: Connection closed>’
In the main dialog pop up screen I see messages like :
‘Connection closed ( skipped due to earlier error, trying again in 8 second(s))’
and sometimes also :
‘ Server returned wrong content-range’
Not after 8 seconds but after some time download may continue but in the end it will fail anyway. During download there is a file in the folder where the file should appear. The name start with a . and has a random extension.
When I hold my mouse over the progress bar I see the name of the file and a download speed around 8-9 MB/s which is good for my 100 Mb network.
The file with the . disappears when the download fails.
After some time the client will start again, and again and again until I delete the file either on the client that sent it or via the web interface.
When I delete it from the web interface the file also disappears from the client that sent it in the first place. When I restore it via the web interface I have the issue on all the clients that try to download the file.
I have no encryption on my Nextcloud server so I can access the files directly via the file system.
On Ubuntu clients I can use rsync to copy the files back to the clients and on Windows I can use FileZilla to copy the files back.
When I have them back on the client the files are oke which means that the initial uploads from the clients which ran without issues are fine.
Steps to replicate it:
I can create any big file on WIndows or Ubuntu some way by for example adding some video VOB files together and put that in a Nexcloud folder.
It gets uploaded but clients will not succeed in downloading it.
In the web interface on the server there is no logging about the failing downloads.
Logging works because I see messages in the logging when I use impersonate to go to any of the 4 users I have in my Nextcloud to delete the big files and clean up the trash cans.

I hope someone can help me so I can add another solution to my list which I keep since version 22.0.0 on GitHub - JackV2020/Nextcloud-Raspberry-Apache-Mariadb: Installed Nextcloud 20.0.4 several upgrades to 24.0.6, kept status green so solved run-time issues.
Many thanks in advance
Jack
. Today I made the changes for the cache and read your comment and increased post_max_size. Many thanks for that. I use base64 encoding and decoding myself in Domoticz python plugins so I know what it is but I was not aware that it was also used for the file transfers by NextCloud.
