OpenVPN AS "Certificate Trust Warning - unable to get local issuer certificate"

Post by TeleBrady » Mon Jun 27, 2022 2:57 pm

Hello,

Posting this here instead of the OpenVPN AS forum as it looks like a better fit (can a mod please delete the other topic?).

My SSL certificate will expire soon, so I was trying to replace it with a free Let's Encrypt one using these instructions.

When I go to upload the new certificate using the web UI and I click "validate", I get a "Certificate Trust Warning - unable to get local issuer certificate" error on screen, but under that the "Certificate/Hostname" shows a match and everything else looks good. From here I revert because I don't want anything to break due to that error, but the current certificate will expire soon anyway.

From what I've read it sounds like I need a separate intermediate certificate(?). Can anyone please tell me what I'm missing or let me know where I need to look to help me figure that out?

OpenVPN Access Server v2.8.5

For now, your original topic seems to fit fine where it is posted.
