Your Cloud Gaming Machine comes with an public IP address, allowing for direct connections to the machine using Moonlight.
When connecting to your Hostmatic Now Cloud Gaming Machine over a mobile 5G connection, you may experience issues where Moonlight can’t reach your gaming PC (Sunshine web dashboard works, and pairing succeeds, but no UDP packets arrive to the client)
This is often caused by your mobile carrier using Carrier-Grade NAT (CGNAT). CGNAT is a type of network configuration that allows multiple users to share a single public IP address. While this is common on mobile networks, it prevents incoming connections from reaching your Cloud Gaming Machine directly, which Moonlight requires for streaming.
Because CGNAT blocks direct inbound connections (the direct peer-to-peer UDP connections), Moonlight may not be able to establish a session when you are on a 5G or LTE network.
If you are affected by CGNAT, you can use an alternative method that supports relayed or VPN-based connections. Applications such as Parsec and Tailscale can help in these cases.
Parsec includes a STUN relay feature that allows connections to work even when both devices are behind NAT, while Tailscale creates a secure VPN tunnel between your devices so that they can communicate as if they were on the same local network.
Either option can help you maintain a stable connection to your Cloud Gaming Machine system when Moonlight cannot connect directly over mobile data.
Support is limited to Sunshine and Moonlight. Use of alternative tools is at your discretion and not covered by Hostmatic Now support.
