Why can't we select a certificate in VPN Phase 1 for authentication?

Question:
I can import a third-party certificate to FLEX/ATP without any errors.
However, I am unable to select this certificate for VPN phase 1 authentication. What could be the issue?

Answer:
ZLD does not support ECDSA certificates in the VPN module, so we cannot select them in Phase 1. Please sign the certificate again with RSA.
