Hello, If you're an OPP user or an uplink node relying on IPsec, please don't upgrade your IPsec router to RouterOS 6.47.  It looks like Mikrotik has changed something significant enough in that release that it's breaking certificate-based authentication.  This broke several of our uplink nodes as they went through upgrades.  We need time to research the new behavior and provide guidance. If you're already familiar with what's broken here, feel free to share! Thanks, --Bart
