It seems they've changed the API being used. I expect the API endpoint we're using may be disabled soon, making it impossible to do arbitrary page requests unless I can find an API YouTube developers forgot to close up. However, it is claimed here that this issue is on YouTube's end. I'll fix the issue for the first page of channels and wait and see whether this issue goes away for other pages
