Proxying with SSL Not Working in .NET Core 3.1

Describe the bug

I am trying to create a proxy with SSL enabled but keep getting the error {"status":"The header name format is invalid."}.

Expected behavior:

Proxy with ssl works.

Test to reproduce

• 1 Create proxy with:

            WireMockServer.Given(Request.Create()
                        .UsingAnyMethod())
                        .AtPriority(100)
                .RespondWith(Response.Create()
                        .WithProxy(proxyUrl));

• 2 Start server with ssl enabled -3 Navigate to https://localhost:[your-port]

1. Proxy without SSL works 2, I am able to proxy with ssl via the Java version of wiremock so I know it’s nothing to do with the website I am proxying to.
