Running this chart configured with nginx causes incorrect redirects and CSP errors

Describe your Issue

When running this chart with nginx enabled, URIs without an ending "/" will cause nginx to redirect with a 301 to "http" instead of "https" (this is of course assuming that you have a reverse proxy serving https as well).

Nginx is the part that is causing this redirect, and it seems like this is solved by adding "absolute_redirect off;" in the server section in the nginx configuration. I would gladly open a PR for this, but I'm not knowledgeable enough about the project to know if this is the best solution.

This issue appears most clearly when trying to enable/disable apps, which will cause a request to https://server/apps/files, which gets incorrectly redirected to http://server/apps/files/

Logs and Errors

Describe your Environment

• Kubernetes distribution: k3s

• Helm Version (or App that manages helm):

• Helm Chart Version:

• values.yaml:

# paste your values.yaml (anonymize any sensitive data)

Additional context, if any

The issue names no file or test; start by locating the chart's nginx server configuration and reproducing a request such as https://server/apps/files without a trailing slash behind an HTTPS reverse proxy. Verify the redirect preserves HTTPS and investigate the reported CSP errors, then confirm the behavior with nginx enabled and the relevant Helm values.
