Describe the bug
Ubuntu 24.04 gui client set wrong ip address - no traffic

[Interface]
Address = 10.9.0.2/24
DNS = 1.1.1.1, 1.0.0.1

after success connect

23: amn0: <POINTOPOINT,PROMISC,NOTRAILERS,UP,LOWER_UP> mtu 1376 qdisc fq_codel state UNKNOWN group default qlen 500
link/none
inet 10.9.0.0/32 scope global amn0
valid_lft forever preferred_lft forever

why set 10.9.0.0/32 not 10.9.0.2/24?
for fix - sudo ip address add 10.9.0.2/24 dev amn0 && sudo ip address del 10.9.0.0/32 dev amn0

Having 2 servers: personal and office. Personal sets IP correctly, office's like described here. Running Arch Linux on all machines.
No valuable differences in the logs.
Setting the address manually helps but useless.

I found bad, but working solution. Set mask to /32 in IP or completely remove it, and IP will be correct.
