Functionality "Refresh Token" in tab "OAuth 2" does not get authentication token

### Expected Behavior

The authentication token should be generated normally, as it was generated in versions prior to version 2021.5.3 regardless of the application environment.

### Actual Behavior

Since version `2021.5.3` I cannot use the **Refresh Token** functionality in a local environment because whenever I click on the **Refresh Token** button I get the error `Failed to fetch token url=https://localhost:5001/connect/token status=0 no description provided`. However, if I point it to any environment other than `localhost`, the functionality presents no problem.

This functionality, until version `2021.5.3`, works without any problems, but since then I can no longer use it with the new versions. Also, when I click on **Response Timeline**, no information is shown on the screen. See the images below:

### Reproduction Steps

1. In the **OAuth 2** tab , enter the necessary data of `grant type`, `access token url`, `client id` and `client secret`;
2. Click on the **Refresh Token** button.

Start by reproducing the failure from the OAuth 2 tab with a token URL on localhost, then compare the Refresh Token behavior with a non-local environment. Done means the token is generated successfully on localhost and Response Timeline displays the resulting information.
