Hello @osman.elhanafy,
Please share output of the command #sh ip int brief
Check if SVI65 is up/up
If yes, try ping 10.250.1.1 with source IP 10.250.1.20.
Does ARP table has got 10.250.1.1 MAC Add ?

I don't see any vlan config there?
9800 needs vlan to be configured, just like you would on a switch.
vlan 65
name ap-mgmt
And "show vlan" should then show vlan 65 active.
Can you see the the nexus in "sh lacp neigh"?
The port should be up if you can see cdp neigh but those ports often require "no negotiation auto" to work but if that's the case you'll see an error in the logs about that.

Port channeling should be forced with 'ON' and not with the use of LACP.
Mine is working this way.

LACP working fine for us.
That was one of the main improvements from AireOS to IOS-XE (although they did remove some of the existing IOS-XE LACP features for some unexplained reason).
