Cannot open recorded video from grid extras node page when running on docker

[lgermani]

Hello,

I'm running some tests using docker-selenium-grid-extras, test execution run without a problem, but if you try to view or download the test recording video, nothing happens.

I recorded what happens to the attached gif:

It looks like it timed out, can you try right clicking and saving the video to your desktop?

[lgermani]

@mariolameiras, same behavior when trying to save the video by right clicking and saving.

I'm not able to replicate your problem. Have you tried smaller or older videos?

Also, change your logs to info and checkout the logs inside /opt/selenium/log

Same problem with small videos.

Changed to debug logs:

environment:
      - SE_OPTS=-debug true

After executing a small test, the video is generated inside video_output folder inside the container.
But I'm still unable to access it via Node Configuration page.

Here is the log:

Onlything i see different from normal at the hub grid_extras log is:
