I have the same error:

[lesca at dodo ~]$ nmcli conn show p6p1 | grep -E '(192.168.61.|ipv4.add)'
ipv4.addresses:

DHCP4.OPZIONE[30]:                      next_server = 192.168.61.254

[lesca at dodo ~]$ LANG=c sudo nmcli conn mod p6p1 ipv4.gateway 192.168.61.250
Error: Failed to modify connection 'p6p1': ipv4.gateway: gateway cannot be set if there are no addresses configured

This occur why the field "ipv4.addresses" is empty, like many other
"ipv4.*" flags:

[lesca at dodo ~]$ nmcli conn show p6p1 | grep ipv4.
ipv4.method:                            auto
ipv4.dns:

ipv4.gateway:                           --

ipv4.dhcp-hostname:                     --
ipv4.never-default:                     no
ipv4.may-fail:                          yes

Some other suggest?

Thanks
