proxy with a endpoint returning a 301 fails to follow the redirect

If the endpoint is reachable but traffic goes thru a proxy, it does reports an error when the endpoint has a 301 (REST endpoint, swagger etc)

Shouldn't you provide an option to follow redirect in the proxy, or follow them by default
