Description of your issue, suggested solution and other information

youtube-dl doesn't work on Nova.cz sites anymore, always fails like above, here on URL http://tn.nova.cz/clanek/tajemstvi-ukryte-v-podzemi-specialni-nemocnice-v-prazske-krci.html#player_13260 which is one of the tests I found still working in a web browser.

The main site https://novaplus.nova.cz/ seems to be completely reworked.

Hopefully someone can fix this. Thanks in advance.

Yes, d6ef8b4 seems to work fine on tn.nova.cz, but still fails on novaplus.nova.cz:
