Hi team - after upgrading signoz cluster using helm on chrome when opening the signoz url getting the below error, have tried looking at the logs for ingress, frontend and they all look good. have tried disabling and enabling ingress as well and doesn't seem to work. any direction on what could cause this? our current setup is k8s installed signoz, with ingress based ssl enabled

Can you try doing a port-forward to the signoz-frontend pod? Just to be sure this isn't coming from your ingress or other network component.

kubectl port-forward <signoz-frontend-...> 3301:3301

And try:

<http://localhost:3301>

yes this is working and loading the default metrics and logs and dashboards as well but thru the load balancer end point it doesn't seem to work

Are you using istio? Otherwise I can't help you.

we aren't using istio - we followed the instructions here: https://signoz.io/docs/tutorial/setting-up-tls-for-signoz/

Since the issue seems to be related to the NGINX Ingress, you could try this tutorial: A Hands-On Guide to Kubernetes Ingress Nginx Alternatively, Istio might be a more robust solution for advanced traffic management. Istio: What is Istio?
