Looking for logfiles of ingress rules and more


an installation in my privat network is working fine with an ingress rufe to forward servername:80 to an http container.
In our company-network the same setup doesn t work. The main differences between the to networkr are
a proxy in the company-network
the node where the http container runs is in another ip-rangs. Rancher, etcd and controlplane abe using and the worker uses
My question:
Wher can I find logfiles for everything around this problem so that I can see if the call of the website reaches the rancher an the ingress-rule and what happens than.
