How did you setup your server and how did you transfer the files to Windows ?

It sounds like the files got corrupted by copying them.

Just wondering if you ever fixed this issue. I am having the same problem on Windows 10 with the OpenVPN connect client version 3.3.2.2475. I am running the OpenVPN server that is packaged with Opnsense and used the export client menu to export the cert, key, and ovpn file. I have also tried the same ovpn profile in another Windows based client (Viscosity) and I am able to connect to the VPN server successfully.

Re: EPKI_ERROR External Certificate Signing Failed

Hello there,
I got the same issue but also present some of my findings.

My tests were done on Win10 with "OpenVPN Gui v11.25" and "OpenVPN Connect 3.3.2 (2475)".
The config with the p12-file (referenced in the config) is working with the GUI. (even without the CA in the config-file)
However the "OpenVPN Connect" can't handle the config (with inline CA).
It errors out with the "Certificate Signing Failed"-Notification. The log actually also says :

Code: Select all

Client exception in transport_recv_excode: OpenSSLContext::SSL::read_cleartext: BIO_read failed, cap=2576 status=-1: 
error:0607907F:digital envelope routines:EVP_PKEY_get0_RSA:expecting an rsa key / 
error:141F0006:SSL routines:tls_construct_cert_verify:EVP lib
"expecting an rsa key" appears to be a real issue! I got the some problem on iOS. However the key and cert-data inline works.
For me this seems like a generic bug!

I wonder if this has to do with:
"Print ec bit details, refuse management-external-key if key is not RSA" from https://community.openvpn.net/openvpn/w ... enVPN2.4.4

OpenVPN-Gui runs on openvpn-2.5.4 (so it's newer than 2.4.4. -- Changelog)
OpenVPN-Connect runs on openvpn3

So this seems to go far deeper as I hoped. I have to open an issue at github apparently.

Any other thoughts on that are greatly appreciated.
