Where are you running these requests? If these were via an in-game script, then it is running on the team create server. The only ones that should be running on your client are plugins and possibly the command bar.
Hi - this is the expected behavior. HttpService requests are all firing from the server side. And such requests will be throttled. Currently there isn’t a special handling case for localhost requests.
And we agree the throttling limit should not apply to requests made from studio plugins, we are working on a fix now and will update here.
