Customer database hidden behind VPN / Proxy

That makes sense if your customer database is behind a VPN or proxy, Adobe sees incoming requests as coming from that shared point, which can obscure the actual source. For more control, consider using an ipv6 proxy. LightningProxies offers IPv6 proxies with massive subnet diversity (2× /29 subnets across 15+ countries), ultra-fast 10 Gbps uplink, unlimited bandwidth and connections, sticky or rotating sessions, back‑connect ports, IP whitelisting, and ~99.9% uptime making it ideal for reliably bypassing VPN/proxy obfuscation and ensuring your actual node is recognized.
