this change doesn't fix video playback at all on catgirl.cloud but if it works for you then sure, why not.

[fpletz]

@999eagle I've had a look, that's actually another issue. The issue being fixed here is that there is no error message show and the player loading/buffering forever. This is currently only broken if DASH combined with proxied streaming is used.

You might need to add services.invidious.sig-helper.enable and generate po_token/visitor_data for your IP/session, see https://docs.invidious.io/installation/#generate-po_token-and-visitor_data-identities. I also needed to fetch videos via a VPN because Youtube blocked the IP ranges of my hoster.
