humm I didn't set a static IP. at least not that I know of. How do I confirm? the only thing different is that a few days ago I configured Rancher via the Docker VM settings to add some containers.

 

[Alecmascot]

There's a couple of lines in the traceback that imply that name resolution is not working.
From the shell "ping www.microsoft.com".
It should resolve and ping the IP address.

pinging google and other sites worked. My docker containers can also reach the internet and my FreeNAS just updated to 11.2 update 1 yesterday. it's only the plugin's config that has this issue. any other ideas?

i meet same problem in FreeNAS 11.2 U7, and i solved it by adding a hostname in /etc/hosts.
you can also enter "network->global configuration", edit "host name database" inputbox , add a hostname record. for example:
192.168.0.2 your_host_name
