LTM SSL handshake failuer (40) with IIS SSL setting Accept

An LTM SSL handshake failure (40) indicates a problem during the SSL/TLS handshake process between the Local Traffic Manager (LTM) and an IIS server. This issue often arises when there’s a mismatch in SSL settings, such as protocol versions or cipher suites. If the IIS SSL setting is set to Accept, it might be allowing weaker protocols, which could cause compatibility issues with LTM. To resolve this, ensure that both the LTM and IIS are configured to support the same SSL/TLS protocols and cipher suites. Additionally, checking the server certificates for validity and proper installation can help eliminate handshake failures.
