I am using https://developers.google.com/youtube/v3/guides/push_notifications to continually monitor ~ 2,000 channels for new videos etc.
Up until last week, I wasn't having any problems, with pubnubsubbub, however, for some reason, I am getting 403 when I am trying to access (via curl or requests) https://pubsubhubbub.appspot.com/subscribe saying nothing more than
<p><b>403.</b> <ins>That’s an error.</ins><p>Your client does not have permission to get URL <code>/subscribe</code> from this server. <ins>That’s all we know.</ins> </p>So my questions are:
- is there any limit (either IP or time or quota) that is documented somewhere and I am somehow hitting? As xml calls were "unlimited" and i do not see any difference in the official YouTube Data Api documentation
- have somebody found a better pub/sub channel (either paid or not) with YouTube DataApi 3
- if somebody had a similar situation, how long my "ban" will stay
