When I rollback to 106.1.0, it works. Hope someone will fix it for next release.

Rolling back to 106.1.0 helps me too. I’ve the same issue at 106.2

Yeah, I admit I messed up trying to satisfy people using full framework, who lost the proxy completely. 106.2.1 fixes it.

Hence that .NET Core will not support the default proxy. You either go without any proxy (default) or specify your own proxy by using RestClient.Proxy property setter.

Full framework version works as before, supporting proxy detection.
