I'm pretty sure paypal is caching my SSL cert for the webhook https://purecore.lhr.rocks, which is unavailable when not on working hours. Whenever I try to use a fresh domain for webhooks and a valid SSL cert, I don't have any issues until the SSL cert becomes unavailable, then, even if available again, it never reports back to that domain.
