[53](https://github.com/video-dev/hls.js/runs/7744598202?check_suite_focus=true#step:8:54)
The browser version selected does not support W3C web protocol tests.
[54](https://github.com/video-dev/hls.js/runs/7744598202?check_suite_focus=true#step:8:55)
To fix this, specify the browser version to be 75 or higher.
[55](https://github.com/video-dev/hls.js/runs/7744598202?check_suite_focus=true#step:8:56)
Or downgrade your test to JWP to test on older browser versions.
