This is my scenario:
a productive work field of 10.11.6 with enterprise proxy settings with authentication.
in the laboratory, we simulated a sierra upgrade with the following surprise:
When the proxy settings are active, we haven’t access to our jss server (no Check-in), checkJSSconnection command does not find anything. It can not even open jss in the web browser, of course it works with firefox.
soon we disable the proxy settings we again connect to our server jss.
some did our own experience? or someone can give me some idea?

our network engineer solved the problem:
to bypass the proxy server do not any longer use an asterisk before the domain name and then it works
