I activated the proxy protocol in the loadbalancer setting menu, but it randomly turned disabled, this has happened 3 times today, for the environment I use kubernetes and add a configmap
apiVersion: v1 kind: ConfigMap metadata: name: nginx-ingress-ingress-nginx-controller namespace: default annotations: service.beta.kubernetes.io/do-loadbalancer-enable-proxy-protocol: “true” data: use-proxy-protocol: ‘true’
what is the cause, has anyone experienced it?

One potential issue could be a conflict between the proxy protocol settings at the Load Balancer level and the NGINX Ingress configuration.
When you specify the annotation service.beta.kubernetes.io/do-loadbalancer-enable-proxy-protocol: “true” in Kubernetes, it should set the proxy protocol at the LB level automatically. But remember, this should match your NGINX Ingress ‘use-proxy-protocol’ settings.
Secondly, a configuration change in your Load Balancer might be overwriting this setting. If you have some script that modifies the Load Balancer settings, it could inadvertently disable the proxy protocol.
Lastly, it could be a bug within the DigitalOcean Kubernetes platform. If none of the above suggestions resolve your problem, it would be worth checking with DigitalOcean Support.
For more information on setting up a Load Balancer and Kubernetes on DigitalOcean, you can refer to this guide.
Hope that this helps!
