Synology OpenVPN fails with "peer certificate verification failure" every few months
Hi everyone,
I'm currently away from home and my OpenVPN connection to my Synology NAS suddenly stopped working. This isn't the first time this has happened. It seems like every few months, out of nowhere, the VPN completely breaks down and cuts me off from my home network.
Since I am remote, I do not have direct access to the DSM to export new config file.
On the client side (macOS, Android), I'm consistently getting the "peer certificate verification failure" error. What's interesting, I have never ever configured any certificates on my Synology.
I already found many different "solutions", but none of them has worked. I tried for example:
- adding client-cert-not-required
- adding tls-cert-profile insecure
- changing verify-x509-name line (or I should say adding, as there was not such line in my config)
- changing OpenVPN Connect security level in settings
- using Tunnelblick
Does anyone know what can I do to fix this without access to my network? And how to prevent it from happening every few months?
