Research direction
Investigate how AdGuard Home's snap package handles file permissions, specifically for private keys. The user can access fullchain.pem but not privkey.pem, indicating snap confinement may be blocking read access to private keys. Check snap interfaces and consider adding a plug for reading certificates or guide users on adjusting permissions.
