go-rancher-gen produces Warnings with Rancher 1.6.15

[HTPC-Schrauber]

Hi,

I had Rancher 1.6.10 with go-rancher-gen which worked fine. Now I upgraded to Rancher Server 1.6.15 and I get Warnings:
29.3.2018 13:32:42INFO[0000] Starting rancher-gen v0.6.0 (ee2ce5c)
29.3.2018 13:32:42INFO[0000] Initializing Rancher Metadata client (version latest)

29.3.2018 13:32:42WARN[0000] Unexpected format of service port: 0.0.0.0:4500:4500/udp

29.3.2018 13:32:42INFO[0000] Executing notify command '/opt/rancher-gen/provision_esb.sh'

What do the Warnings mean?
go-rancher-gen seems to work without problem, but I am still not sure if I can savely ignore the warnings.

Kind regards

It seems that in a newer version of rancher api they prefix the service port with the IP address.
It shouldn't be a problem but i will check if i am able to fix it.
