Description

using LE generated cert for openvpn config
openvpn client can't connect stopping at

 VERIFY ERROR: depth=1, error=unable to get issuer certificate: C=US, O=Let's Encrypt, CN=Let's Encrypt Authority X3

seems to be due to ca certificate got by acme client is the crosssigned one lets-encrypt-x3-cross-signed without being bundled with root cert

got it to work by changing LE ca cert (on cert manager) to the letsencryptauthorityx3 bundled with isrgrootx1

using openvpn cli and network-manager on ubuntu 16.04.3

Never use a public/globally trusted cert with your VPN. You will allow anyone anywhere with a cert from the same CA access to your VPN, reducing your overall security even with additional layers like TLS keys.

Use a self-signed CA/Cert structure. There is zero benefit to using an ACME or other trusted cert and massive disadvantages by doing so.

We will not fix an issue that would degrade security in this way.

you're right, It's better using own CA for private vpn

but the issue is about ACME client to put the bundled LE CA cert in cert manager then deliver the whole bundle to connected clients, so that more clients will be able to validate certs issued by LE.
aside from openvpn, can this benefit to other services? haproxy?

No. It already works fine with all other services that we're aware of, including HAProxy.
