Unable to add an IP address to IP Access Rules

Nope - no antivirus or anything like that.

When I connect to this URL for example: DevTools failed to load source map: Could not load content for Cloudflare | Web Performance & Security HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

All I receive is Not Found.

When I try: https://dash.cloudflare.com/api/v4/zones/c2173bbfa54a8e079c2bd86acbcd1432/subscription

I receive:
