Disable tls
Under the OS (w2022) using IISCrypto and verifying with the registry, TLS1.0 and TLS1.1 appears disabled.
Is there anything under the IIS application that would try to use the older TLS? How can I find it?

Capture and analyze traffic between the server and clients. By inspecting the handshake of TLS connections, you can determine if any connections are attempting to use older protocols like TLS 1.0 or 1.1. Checkout this article which will help you capturing the network traffic - How to Capture Simultaneous Wireshark Traces from Client and Server for Network Troubleshooting (microsoft.com). Filter by tls.handshake to see the version of TLS being negotiated during the SSL/TLS handshake.Look for Client Hello and Server Hello messages to see which protocol is being requested and accepted.
