403 forbidden when using proxy wiremock in c# unit test

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

I’ve created an unit test using wiremocknet. I’ve setup so that instead of targeting https://mycompany/private/ it instead target http://localhost:8080/ that forward it then to the https://myco mpany/private

By using Wiremockserver.Start and setting a Logger and an proxyAndRecordSettings.

The issue is that I always have 403 forbidden.
I know that the forward work otherwise I would have no response.
I know the header with authentication are correctly feeded to my http client as I have only switch the url.

By using postman I can see my header correctly fed (if I’m not mistaken)

But it seems wiremock net jinx my auth

Correct forward of header for auth when calling api in forward and record mode

Describe alternatives you've considered
Installed wiremock Java locally to do the forward and record and it worked

Is your feature request supported by WireMock (java version)? Please provide details.
Wiremock Java locally works but I want the net version to be able to have an unit test that record all call to external api so that after record all call are mocked and stored
