Nextcloud version (eg, 20.0.5): 26.0.2
Operating system and version (eg, Ubuntu 20.04): Debian with Docker (fpm-version)
Apache or nginx version (eg, Apache 2.4.25): docker: nginx 1.21.6
PHP version (eg, 7.4): 8.2.6
The issue you are facing:
When using HTTP/2 and uploading folders, I get on a few (random?) files the error
expected filesize is 10485760 but read 10477568
the difference is always 8192 bytes…
2nd problem: while uploading big files – as soon as they were chunked, on webinterface, there is no remaining time any more on the upload-bar, just “uploading…”
Is this the first time you’ve seen this error?
No, I see thin on all of my instances (2 schools, 1 private)! With different setups (all with docker):
-
server: Nextcloud v24 with
nextcloud:apache(docker/docker-compose.yml at master · nextcloud/docker · GitHub) behind Traefik v2. When conecting to the Nextcloud-container directly via port-forwarding, the connection is on HTTP/1.1 → all working. Traefik makes HTTP/2-connections → problems! -
server: Nextcloud v26 with
nextcloud:fpm-alpine(docker/.examples/docker-compose/insecure/mariadb/fpm at master · nextcloud/docker · GitHub) behind Traefik v2. Same problem.
Try on 2. server: activating HTTP/2 on nginx-container and connecting directly via docker-port-forwarding (ports: 12443:443) → same problem! (nginx configuration from here: NGINX configuration — Nextcloud latest Administration Manual latest documentation)
So always when connecting with HTTP/2 activated – with or without Traefik-proxy – the problem appears.
Steps to replicate it:
- Docker with Traefik proxy
- use docker/docker-compose.yml at master · nextcloud/docker · GitHub (or fpm-version) with traefik-labels
app:
networks:
- default
- proxy
labels:
- "traefik.enable=true"
- "traefik.http.routers.nextcloud.entrypoints=http"
- "traefik.http.routers.nextcloud.rule=Host(`nextcloud.***`)"
- "traefik.http.routers.nextcloud.middlewares=https-redirect"
- "traefik.http.routers.nextcloud-secure.entrypoints=https"
- "traefik.http.routers.nextcloud-secure.rule=Host(`nextcloud.***`)"

- Upload a folder with many (~30) big files

“Solution”
When disabling HTTP/2-Mode on client side in Firefox (about:config → network.http.http2.enabled = false) all works as expected!
But that is only a solution for my private Nextcloud-server (and only for Laptop, not for iPad,…), not for my schools…
So where are the problems with HTTP/2?
Thank you an greetings
Alex
Edit:
I tried following:
Firefox — HTTPS/1.1 —> Traefik — HTTPS/2 —> Nextcloud (nginx-fpm)
That seems to work…
not working:
Firefox — HTTPS/2 —> Nextcloud (nginx-fpm)
Firefox — HTTPS/2 —> Traefik — HTTP/1.1 —> Nextcloud
Firefox — HTTPS/2 —> Traefik — HTTP/2 —> Nextcloud
furthermore: I tried with Chrome and it seems to work:
Chrome — HTTPS/2 —> Traefik — HTTP/2 —> Nextcloud
why? 
Edit 2
I tried uploading one folder with chrome. And then simultaneously with Firefox (via HTTP/2!) and it crashes totally!
The tmp-files stuck:
and neither in chrome nor in firefox the upload goes on…
no files are uploaded correctly. After stopping uploading in firefox, the upload in chrome goes on without any more problems…
Simultaneous uploading with Chrome on HTTP/2 and Firefox on HTTP/1.1 is working fine!
but maybe this article from cloudflare helps you a little
