Meteor / Hot Code Push: Error: certificate has expired

Hey folks - a production app is having HCP issues. It’s throwing the following error but I’ve never seen it before. Does anyone know what might be it?

[autoupdate] Download failure: error downloading asset manifest: Error: certificate has expired

Oddly enough, staging environment works perfectly

Do you have Push Notifications? I’ve seen a similar issue when the server certificates for iOS are invalid or have expired.

No push notifications, looks directly related to HCP
