PolarSSL Error: PK-Key algorithm is unsupported

I am trying to connect to my VPN server using the OpenVPN Connect Android app with my Galaxy S4. My CA certificate was generated using OpenSSL and not easy-rsa. It is using ECDSA with the NIST secp384r1 curve which PolarSSL reports as compatible here: https://polarssl.org/core-features. However, after importing my .ovpn and attempting to connect, it hits me with this error:

PolarSSL: error parsing ca certificate : PK-Key algorithm is unsupported (only RSA and EC are supported)

I am able to connect to this VPN server with both Windows and Linux clients.
