Hi Gris,

I wasn't able to understand the reason of the hang from the logs attached, and I can't reproduce the issue either.

I have prepared branch bg/rh1782701 of NM with additional debugging log messages; could you please reproduce the problem with that NM version and attach logs? Thanks!

nmstate is waiting on `state-change` signal from NM.Device or NM.ActivateConnection.
But nmstate failed to get callback for 30 seconds and the activation
stuck at NM_ACTIVE_CONNECTION_STATE_ACTIVATING.

You need to try many times before hit this problem.

Will do.

Hi Beniamino,

With NetworkManager-1.22.7-24666.dbd7083881.el8.x86_64, I got no NM_ACTIVE_CONNECTION_STATE_ACTIVATING hang failure.

Thanks.
