cURL does not work but same site works with browser

Look browsers headers while sending your request, and add same headers to cURL request. Some servers needs some headers that browsers sends default but not cURL.

To avoid/suppress SSL error, use -k flag, ie

curl -k ...

I had 301 Moved Permanently error on curl but was working on browser.

But when I looked deeper there's Location to moved to location, which would be working. This coulde be when the server is using TLS.

Also, you can goto brower and see the network which will have headers information.
