We have an AWS VPN Client Endpoint set up and are using OpenVPN as the client to connect. This has worked with no issues until today. I don't see any outages that are relevant and the error message we're getting is:
Lost connection to server : 1 times
The Client VPN endpoint is still showing as available in AWS:
Certs are valid until next year and the CA is valid until 10 years from now.
Nothing has changed that I know of since we were able to connect. What steps should I take to troubleshoot this further?
Nothing I tried resolved the issue. I recreated a client VPN endpoint with the same settings and it works fine. I deleted the old one and notified everyone of the updated endpoint. Weird.
