We created a root crtificate, which unfortunately expired today in Azure VPN, I regenerated the certificate, upload it to Azure VPN, regenerated a client certificate and se up the OpenVPN configuration file. (After downloaadin the "VPN Client" from the Azure portal.
However, I keep getting "Peer certification verification failure" and I can't seem to understand why. Everything I read suggests that it is as there is a mismatch between the server and the client, however, I must be making the same mistakes, as I have followed the instructions below to generate the root certs, and the client certs::
- I had been using a windows version of OpenVPN to test the connections were working, by the looks of it, some versions of OpenVPN return the "Peer certification verification failure" error, although this is not the case. You need to download version 2.5.4 from https://openvpn.net/community-downloads/ instead of the latest and this seems to not have the same issue (I had originally installed vrsion 2.5.7.)
Hope that helps...
