500: Failed to connect to my Hub at http://hub:8081/hub/hub/api

Thanks @consideRatio for your response. Yeah we have our own network policies to talk between two namespaces. I disabled network policies as part of the helm chart. Also, i have the RBAC permissions enabled to talk from hub namespace to singleuser namespace. Regarding the base url i enabled this in helm chart this is due to our ingress rules. Technically this can be removed but i haven’t tested it yet.
I also have another question would be great if you can take a look at this.

Appreciate all your help.
