Enabling Require SSL in Internet Information Services (IIS) for any subfolder under the Snow License Manager site will cause a "The connection was reset" error, preventing access to pages in that subfolder.

IIS SSL Settings (Ignore / Accept / Require) operate at the HTTP application layer, after the TLS handshake is completed by HTTP.SYS (Windows kernel-mode HTTP listener).

When the root is set to “Ignore” SSL (the default setting for Snow License Manager), you are effectively telling IIS: This site does not expect HTTPS traffic.

This creates an inconsistent configuration with having an HTTPS-only binding, because:

• The binding says, "this site only listens for HTTPS."
• The IIS root configuration says, "this site does not expect SSL."

This mismatch causes HTTP.SYS to terminate the connection before IIS can process the request, resulting in:

• TCP reset (ERR_CONNECTION_RESET)
• Abrupt closure after the TLS ClientHello phase

Because the failure occurs at the transport layer, the subfolder’s settings are never reached.
