I'm facing a strange issue where I can successfully access the MinIO Console using curl and nc on port 9001 from my MacBook, but when trying to open the same address in a browser, the page doesn't load and doesn't show up.

Current Setup:

• MinIO is running in a Docker container on my Windows desktop machine.

• Nginx is used as a reverse proxy to forward requests to MinIO Console on port 9001.

• When I run the following commands from my MacBook, I get normal responses:

  curl -v http://<server_ip>:9001
  nc -vz <server_ip> 9001
  

  Both commands return successful responses (HTTP 200 for curl).

However, when I try to access http://<server_ip>:9001 via my browser, the page doesn't load correctly — it doesn't show up.

Additionally:

• Script Issue: I have a script on my MacBook that saves a test bucket and test files to MinIO on the desktop. When I run this script, I get the error no route to host. However, if I run the same script with sudo, it works fine.
• User: I am using a single user account on my MacBook, and the issue happens intermittently. Sometimes everything works, sometimes it doesn't, and I can't pinpoint the cause.

What I've Tried:

• Permissions: I checked the firewall and port settings. Ports 9000 and 9001 are open and accessible.
• Browser Issues: I've tried clearing cache and using incognito mode. Still, the issue persists.
• Nginx Configuration: Nginx seems to be working properly, as curl and nc work fine.

Questions:

• Why can I access the MinIO Console with curl, but not with the browser?
• What could be causing the intermittent behavior (sometimes it works, sometimes it doesn't)?
• Why does the script only work with sudo?
• Is there something I could have overlooked in my Nginx or MinIO configuration?
