Flurl.Http.FlurlHttpException: 'Call failed. The archive entry was compressed using an unsupported compression method

[totalgit74]

I've setup a request for an internal company url with header accept application/json and 120s timeout.
I've tried await request.AllowAnyHttpStatus().GetAsync() and keep getting...

Flurl.Http.FlurlHttpException: 'Call failed. The archive entry was compressed using an unsupported compression method: GET <url>'

Inner Exception
InvalidDataException: The archive entry was compressed using an unsupported compression method.

This same code was working previously and if I perform curl -X 'GET' '<url>' -H 'accept: application/json' from a git bash window the call works and returns JSON.

How do I begin to even diagnose what Flurl is seeing that it cannot process? I feel that if I use a native .Net client I may get a different result any way.

Using Flurl.Http 4.0.2 with .Net 6
