I am trying to test the Authentication call after I have followed all the steps for creating all the needed headers. However I keep getting public role.

I have double and triple checked but the digest and signatures match exactly with the online tools provided by you.

Any ideas on why this might be happening?

One thing that I would like to mention is that I am using a proxy because I could not send the request otherwise via localhost (CORS does not allow it and I am using an ionic application). Could that be the issue? Even though I have already tried adding in the host header the proxy prefix but still no success.

I am sending my requests via axios.

Network tab in chrome provided the following info.
An example of what I am sending for the request is:
