    Geneve tunnels between NSX-T Edge and ESXi stopped working.

      Hello,

       

      Today, suddenly the Geneve tunnels between NSX-T Edges and ESXi have stopped working.

       

      Changes have been made since it was working, but I have no idea what the error was. I tried to revert as much as I could remember, but it's still not working.

       

      Here is a screenshot of the tunnels on one of the NSX-T Edges:

      And the tunnels on the ESXi host (all are down to all NSX-T Edges):

      I logged into the esxi host to check the vmknics and routes (showing both default routes and vxlan stack routes):

      I also tried to ping the addresses from a system connected to the 192.168.20.0/24 network and I am able to ping the edges tunnel IPs (192.168.20.200 and 192.168.20.201), but I cannot ping the ESXi tunnel addresses (192.168.20.202 and 192.168.20.203)

       

      I'm at a total loss.

       

      All help would be appreciated, I really do not want to remove NSX-T and redeploy everything again as it was an adventure to deploy it the first time. (though if it's broken beyond repair then I have no choice)

       

      Kind regards,
