[🐛 Bug]: Cannot upload (manually or through selenium)

[alvitawa]

What happened?

I cannot upload files in the docker standalone. Neither through manually selecting a file on noVNC or through selenium. When doing it manually I can select a file but then it just does nothing. With send_keys also nothing happens. Happens both on selenium/standalone-firefox:latest and selenium/standalone-chromium:latest
(if I run it locally on chrome it works fine of course)

Also, saving the website with Ctrl+S fails, not sure if it is related:

Command used to start Selenium Grid with Docker (or Kubernetes)

#!/bin/bash

docker stop selenium-grid
docker rm selenium-grid
docker run -d \
  -p 4444:4444 \
  -p 7900:7900 \
  -v $PWD/tests/share:/home/seluser/Downloads \
  --shm-size="2g" \
  --name=selenium-grid \
  --network testing-network \
  selenium/standalone-firefox:131.0-20241024
#  selenium/standalone-firefox:latest
#  selenium/standalone-chromium:latest

Update: It doesn't happen when testing a public url, but when testing a webserver hosted locally but on a different docker container (as a part of the same network).

The container with the webserver is started with:

docker run --rm -t \
  --memory=2g \
  --cpus=1 \
  --name cvscooter_run_web \
  --network testing-network \
  --network-alias docker.sw.cvscooter_run_web \
  --network-alias dev.sw.cvscooter_run_web \
  -e CONFIG=$CONFIG \
  -e INSTANCE=web \
  -e PORT=80 \
  -p 80:80 \
  cvscooter_image_web

Solved by configuring a local certificate with mkcert and serving the endpoint through https. Strange that this is necessary.
