Okay a nested environment. It doesn't look like any of your tunnels are up. Since it's nested have you configured the vSS/vDS on the top level host to support jumbo frames? Geneve needs at least 1600 although larger is recommended, what you have configured will be available on the uplink profile you applied to your hosts in NSX as it is configurable. Whatever you have set (I believe the default is 1700) set the top level vSS/VDS to that.
I'd also configure the top level vSS/vDS to support tagging by apply 5095 to support tags.
