Tunnel connexion problem since build 90

Post by gpascal » Fri Nov 03, 2017 3:25 pm

I have an openvpn server 2.2.1
Since few days, users with openvpn connect updated their application to 1.1.23 (build 90) and since then, no one tunnel can be reached.

This error appear: mbed TLS: SSL read error: X509 - Certificate verification failed

Log fail say: VERIFY FAIL -- THe certificate is signed with an unacceptable hash

Comptability problem seems appear no?

Can you help me with this?

Thanks a lot

OpenVPN 2.2.1 is no longer supported and you should upgrade A.S.A.P.

this error sounds more like your cert is signed with md5.
this is really unsecure and your certs should all be upgraded if possible.
