[bug]: Import/Export plugin returns 401 Unauthorized on Strapi behind Apache proxy with HTTPS

[dineshpithiya-virtusa]

What version of @strapi/sdk-plugin are you using?

Describe the bug

I am trying to use the Strapi Import/Export plugin (https://market.strapi.io/plugins/strapi-import-export) on Strapi v4 running behind an Apache reverse proxy with HTTPS on AWS EC2.
Whenever I try to export content types, I get the following error in the browser console:

What's Wrong?

POST https://strapi.dev2.mybrainguide.org/strapi-import-export/export/contentTypes
401 (Unauthorized)
FetchError: Missing or invalid credentials

The plugin never completes the export and the frontend shows "fetching data" indefinitely.

---

Steps to reproduce

1. Deploy Strapi v4 on Ubuntu AWS EC2.
2. Configure Apache as a reverse proxy:

HTTP virtual host (*:80)

<VirtualHost *:80>
ServerName strapi.dev2.mybrainguide.org
RewriteEngine on
RewriteCond %{SERVER_NAME} =strapi.dev2.mybrainguide.org
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

HTTPS virtual host (*:443)
<VirtualHost *:443>
ServerName strapi.dev2.mybrainguide.org

bash
Copy code
SSLEngine On
SSLCertificateFile /etc/letsencrypt/live/strapi.dev2.mybrainguide.org/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/strapi.dev2.mybrainguide.org/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf

ProxyPreserveHost On
ProxyRequests Off
ProxyPass / http://localhost:1337/ retry=0
ProxyPassReverse / http://localhost:1337/
ProxyTimeout 300

RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-Port "443"
```
Log into Strapi admin panel over HTTPS.

Go to the Import/Export plugin.

Attempt to export any collection type.

Expected Behaviour

Content types should export successfully, and JSON should be returned to the frontend.
