Which Ubuntu version do you recommend I use?

20.04

not sure if that’s the root cause of your issues, but it might get you a little closer. If you don’t have any specific network rules setup for those nodes, my guess would be the OS with this info you’ve provided.

OMGGGGG THANK YOU!!!! I’ve been trying to get this to work for that last 6 days! Switching to Ubuntu 20.04 (LTS) did the trick!!!!!
