Hi,

The error related to AMF might be due to the UPF not being activated yet.
Regarding the UPF error, could you provide more log details? That would help with further analysis.
Also, please make sure that the PLMN configured in the core network matches the one on your gNB.

Best regards,
Peggy

Hi,

Is there any other warning or error before this one?
We’ll need more information to make an accurate guess.
But first, you can check whether the N6 interface is configured correctly.
