Currently if there is a brief network issue or outage, these requests may fail causing an HTTP 500 to be received on yt-dlp end and no PO Token added to the request.

Perhaps a basic retry (with a limit) could be added to requests (e.g. retry 3 times before giving up)?

Adding retries as part of #44
Do you think your plugin framework should also attempt a retry if not PO token was received from the provider? Or at least throw a specific error so that the user knows what happened.

I think this would be up to the provider plugin to implement, as it is dependent on the implementation whether it can be retried or not.

Or at least throw a specific error so that the user knows what happened.

It does raise a warning if a RequestError is thrown
