### What happened?

i have deployed litellm via helm chart. the ingress controller speak "http" with the outside part of cluster. outside cluster i have a tls termination, so client arrive via https

the drawing is

https --> NGINX ---> http --> KUBE --> http --> litellm

what happen often and it's hard to track for me is that i got a few redirect to http

example

` http://litellm.k8s.fabrick.dmz.tst/ui/login/?redirect_to=https%3A%2F%2Flitellm.k8s.fabrick.dmz.tst%2Fui%2Fmcp-servers%2F `

the "redirect_to" is actually correct (https) while the 'real' redirect was http

i did set in the helm chart

``` envVars: PROXY_BASE_URL: "https://litellm.k8s.fabrick.dmz.tst" FORWARDED_ALLOW_IPS: "*" ```
