Alright @Dany and @helge
Good to know you could get the 3node to work properly, especially knowing you got it working with upgrades instead of buying a new NIC card. That’s nice! I’ll check the video. Looks interesting.
I will document the solution you found here as I think it will be quite helpful for future TFarmers.
As you proposed @Dany I closed the post as the solution was found!
Thanks for the feedback!
