OpenVPN Support Forum

Hello;

I'm having a problem using OpenVPN in iPhone cause I'm trying to use an archive created by CMR2020 that use Pre-shared key and I'm gettind the error:

OpenVPN error: mbed TLS: ca certificate is undefined.

what can I do?

Thanks in advance.

I believe that your iPhone does not support "pre-shared key" method so you need a proper PKI.
