Until two days ago I used OpenVPN to connect to my workplace, on a
non-security sensitive tunnel (just for convenience).

However, OpenSSL updated on my machine (Fedora 26), and now the
certificate is rejected:

Fri Oct  6 17:25:06 2017 OpenVPN 2.4.4 x86_64-redhat-linux-gnu [SSL
(OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on

2017, LZO 2.08
Fri Oct  6 17:25:06 2017 OpenSSL: error:140AB18E:SSL

Fri Oct  6 17:25:06 2017 Cannot load certificate file lcs/delentef.crt
Fri Oct  6 17:25:06 2017 Exiting due to fatal error

What solutions are there to this problem? Can I configure OpenSSL to
accept this certificate after all?
