Version of Helm and Kubernetes:
AWS EKS 1.33, chart version 1.50.0

Which chart:
pgadmin

What happened:
after authentication with GitHub and EAS / oauth2-proxy, and logging into pgadmin
file upload in pgadmin storage manager breaks after about one minute.
also some long running queries inside pgadmin break.
(using k9s kubernetes port-forward allows for very long session time without this issue)

What you expected to happen:
according to settings in all components, session should last 24hrs.
expected to do file uploads of 2GB files / 5 minutes and have long-running queries.

How to reproduce it (as minimally and precisely as possible):
traefik chart 36.3.0 and oauth2-proxy, and without middleware in traefik

[KorenP1]

it is not an official pgadmin helm chart so i dont think that this is the correct repo for supporting this case.
Ill just mention that file uploads to pgadmin have a limit, i would check if you need to increase that limit in pgadmin or with an annotation with your ingress controller.
