Digi Passport 32 Switch LAN connection is lost

The connection is lost every time a LAN uses a device.I can’t connect the Console-Server via SSH and HTTP. Ping doesn’t work.
After reboot everything is working again.

This looks like it would require quite a bit more information to further diagnose.
Please open a case with Digi Support. You can do this by sending an email with details to tech.support@digi.com
The problem description in detail, product, serial number, and firmware revision would all be helpful to include.

Thanks Ronk.
