We have a strange behaviour with our Cisco Business 220 Series Switch. We want to put a Reverse Proxy in front of the Cisco Switch. But in doing so a login to the admin gui is not possible anymore. We always get this error response from the switch:
Login with the same user/pwd directly without the reverse proxy does work without any issue.
The Reverse Proxy is listening on https, connection to switch is http.
Has anyone an idea what's wrong with it?
