Argo CD OIDC "invalid audience" / "failed to verify signature" — Using Dex and AWS IAM

[leslie885]

I am running Argo CD with Dex and AWS IAM for OIDC authentication, but I keep getting an “invalid audience” and “failed to verify signature” error.

In addition, the Argo CD UI keeps blinking on and off — sometimes I can see the deployed application, and other times it disappears.

I have already checked the connection and API, and everything seems fine. I also added session stickiness to the load balancer, but the issue persists.

Has anyone experienced this before or knows what might be causing it?
