SSL_CTX_use_certificate:ca md too weak

[agowa338]

Hello,

I've a openvpn server set up and I'm also able to connect to it from multiple devices.
But one a notebook with archlinux throws the following error message when attempting to connect:

Sun Jun 18 20:47:41 2017 OpenVPN 2.4.2 x86_64-unknown-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on May 11 2017
Sun Jun 18 20:47:41 2017 library versions: OpenSSL 1.1.0f 25 May 2017, LZO 2.10
Sun Jun 18 20:47:41 2017 OpenSSL: error:140AB18E:SSL routines:SSL_CTX_use_certificate:ca md too weak
Sun Jun 18 20:47:41 2017 Cannot load certificate file client.crt
Sun Jun 18 20:47:41 2017 Exiting due to fatal error

What's wrong here? I've researched that error and as I read, it is only thorwn, if the root certificate is md5 signed, but it is sha256, any idea?

My Certificate:

Code: Select all
