[Lahbak]

After running AMF
cd $GOPATH/src/free5gc
./bin/amf

it shows me this message at THE END :

How to resolve this problem please ?

[endrigoshi]

It seems that it cannot register itself to the NRF. Are you running NRF before running AMF?
Or it can be a configuration problem, where NRF is not running at 127.0.0.1 as is specified in the config file.

i run the nrf

But when i run the other function I find the same problem :
register to NRF Error[Put https://localhost:29510/nnrf-nfm/v1/nf-instances/eca51c70-27c1-4530-bfc3-9e16e3475de5: dial tcp 127.0.0.1:29510: connect: connection refused]

[endrigoshi]

Are you running the AMF and NRF in the same machine, or in different ones?

[Lahbak]

on the same machine
