Could not store JavaScript player

Could not get player js code from url: https://www.youtube.com/s/player/c2199353/player_ias.vflset/en_US/base.js

Do you have some details and/or the complete exceptions, including the ones which are ignored, since you're using the debugger? We saw this issue multiple times and we'd like to fix it.

Edit: your issue is a bit different, as that's when the player is fetched that the issue happen.

We could may be send more headers to make the JavaScript player request being like a request made by a web browser:

Origin: https://www.youtube.com Referer: https://www.youtube.com Sec-Fetch-Dest: script Sec-Fetch-Mode: no-cors Sec-Fetch-Site: same-origin

(And maybe do the same process for the embed YouTube HTML page and the iframe API request.)

Ran into this error, here's the exception I got, hopefully it helps. (EDIT: Turns out one of the blocklists in my DNS resolver was updated to include youtube.com for some reason. Problem was resolved when I disabled that blocklist, so this might be a different issue than what OP encountered.)

Exception

• User Action: requested stream

• Content Country: US
• Content Language: en-US
• App Language: en_US

Closing due to lack of author's response.

Are you on Android? I had same issue and fixed it by adding internet permission and executing http request on io thread
