argo-cd: Unable to login against ingress: FATA[0007] rpc error: code = Internal desc = transport: received the unexpected content-type "text/plain; charset=utf-8

Describe the bug After creating an ingress I am unable to login

To Reproduce Steps to reproduce the behavior:

1. Apply ingress.yaml
2. Go to ‘argocd.svc.dev.intra’
3. Enter username and password
   • Password is the one from kubectl get pods -n argocd -l app.kubernetes.io/name=argocd-server -o name | cut -d'/' -f 2
4. Click sign in

Expected behavior I am logged in the same way as it happens when I connect to https://localhost:8080 when doing with port forwarding

Additional context

Login via client:

When try to login via client I get

argocd login argocd.svc.dev.intra
Username: admin
Password:
FATA[0007] rpc error: code = Internal desc = transport: received the unexpected content-type "text/plain; charset=utf-8"
