I have an arcgis server installed on a Windows 7 machine, it is already using https, but without a valid certificate.
To configure WebAdaptor, use the https server link https://myhost:6443 and after configuration do not access the web adapter with https, only http. Now via webadaptor, go to http://myhost/arcgis/manager.
Without using webadaptor or https it works perfectly.
Why is this happening?
