awg-quick can't up interface with peers preconfigured

[onyx-zup]

aws instance, amnesiawg can fire up awg0 only with no peers in awg0.conf, otherwise "Unable to modify interface: Operation not supported" error

• status: awg started and running with no peers

root@aws-client:/etc/amnezia/amneziawg# cat awg0.conf 
[Interface]
Address = 10.11.0.5/32
PrivateKey = |clent-privkey|

• here am adding server peer with 'awg set awg0 peer |server-pubkey| endpoint ......' and running some iperf tests

• here im shutting it down

root@aws-client:/etc/amnezia/amneziawg# awg-quick down awg0 [#] ip link delete dev awg0

- and trying to start over again

root@aws-client:/etc/amnezia/amneziawg# awg-quick up awg0 [#] ip link add awg0 type amneziawg [#] awg setconf awg0 /dev/fd/63 Unable to modify interface: Operation not supported [#] ip link delete dev awg0

# it will not start until i remove Peer section from awg0.conf

Yes, i have kernel module installed and running

# lsmod |grep wg

You don't have to delete all "[Peer]" sections. "AdvancedSecurity = on" strings will be enough. That's weird, but works for me. :-/

Confirmed! this setup works pretty stable for me

Kernel module has been updated and this problem should have been fixed. Please check out and re-open this issue if needed.
