The EPM Windows installer blocks the installation because it cannot negotiate TLS 1.2 or TLS 1.3 with Segura™ Platform on port 443. This document covers EPM Windows 4.2.17.
Symptom
- The installer stops with a message saying it could not negotiate a secure connection. The message says Segura® Platform must accept TLS 1.2 or TLS 1.3 on port
443. EPM Windows is not installed. - The Windows Event Viewer records the error in the EPM log, usually with event ID
18001. The Details part of the event shows the reason.
Cause 1: Segura™ Platform does not offer TLS 1.2 or TLS 1.3
Segura® Platform accepts neither TLS 1.2 nor TLS 1.3, so the installer finds no protocol version in common.
Solution: Enable TLS 1.2 or TLS 1.3 on Segura™ Platform
- Enable TLS 1.2 or TLS 1.3 on Segura™ Platform.
- Run the installer again.
Cause 2: TLS 1.2 is disabled on the workstation
TLS 1.2 is disabled in the workstation's Windows, for example by a hardening policy.
Solution: Re-enable TLS 1.2 on the workstation
- Check that TLS 1.2 is not disabled on the workstation's Windows.
- Run the installer again.
