Hello,
we are currently experiencing a recurring issue with our SpeedFusion Cloud (SFC) infrastructure setup.
Our configuration includes three tunnels to different endpoints:
- SFC-ZRH (primary)
- SFC-PAR
- SFC-HEL
We have observed that when the primary tunnel to SFC-ZRH fails, the entire router goes offline and becomes unreachable via InControl2.
Please see the below screenshot illustrating the issue:
- In the moment the tunnel to SFC-ZRH fails, the cellular modules are shown as offline within that tunnel, although they are still active and connected in the other tunnels (PAR/HEL).
- Starlink on WAN1 remains online, though it exhibits increased latency during the event.
After removing and re-adding the SFC-ZRH tunnel, the connection restores and everything works again as expected.
We are seeing this behavior across multiple devices:
- MAX HD4 MBX 5G
- Balance 580
- Balance 305
This occurs under both Firmware 8.5.1 and 8.5.2.
We would appreciate your support to help us identify and resolve this behavior or ideally a way to prevent the router from going offline.
Thank you in advance!
Best regards,
Matthias
