Hi @MassiveCyanSeal,

I haven’t seen such an issue before however after some research, this seems to be a bug with nmtui. What seems to fix the issue is the

ipv4.method manual 

option.

Basically, what seems to work is:

 nmcli connection modify ether-enp1s0 ipv4.method manual ipv4.addresses XXX.XXX.XXX.XXX/24 ipv4.gateway XXX.XXX.XXX.XXX ipv4.dns XXX.XXX.XXX.XXX

Where XXX.XXX.XXX.XXX are your IP addresses accordingly to what’s needed.

Hope this helps!
