Private Network Protector

Hi All,

I am working with an application that uses go-libp2p but when starting the application which was compiled on my Ubuntu 20.04 with go 1.17.2 but I am getting an error:

“tried to create a libp2p node with no Private Network Protector but usage of Private Networks is forced by the environment”

I tried to also export the environment variable:

export LIBP2P_FORCE_PNET=1

but still get this error.

Any ideas what is causing this?

Thanks in advance
