Magento 2: 403 Forbidden error when trying to get admin token

I am an administrator for a magento 2 application and I am struggling to get my admin token via the magento 2 API. The API call that I am making is to the following endpoint configuration: POST {host}/rest/{store_code}/V1/integration/admin/token.

I am able to login with my username and password to the admin dashboard, and I can see on there that my user is listed as an administrator with access to all resources. But for some reason, whenever I post to that url endpoint with valid credentials, I get a 403 forbidden error.

I am an administrator for another magento 2 application as well, and when I followed the same convention for retrieving an admin token for this other application, it worked just fine. I am unsure of why I would get a 403 forbidden error if my user is set to be an administrator.

Does anyone have any troubleshooting tips or where I could check first to see what may be the problem?
