> h1. Problem
> When trying to consume a SOAP service with a server that doesn't accept
> HTTP/2 under HTTP, the Apache-CXF agent doesn't downgrade the protocol to
> resend the request with HTTP 1.1.
> h1. Context
> I'm trying to consume a SOAP service. The service is exposed via HTTP. The
> problem is that when consuming this service I get the following error:
> {code:java}
> Caused by: org.apache.cxf.transport.http.HTTPException: HTTP response '403:
> (POST

> Further beyond the error, I used wireshark to access the request and
> response. The thing is that Apache is using HTTP/2 and the server doesn't
> accept this protocol, so it denys the request as we can see in this image:

> When I change the client to use HTTP 1.1, it works correctly:
> {code:java}
> Client client = ClientProxy.getClient(myService);
> HTTPConduit http = (HTTPConduit) client.getConduit();
> http.getClient().setVersion("1.1");
> {code}
> !image-2023-09-01-12-06-40-208.png|width=650,height=402!
> So, shouldn't it work just out of the box (the client negotating with the
> server) without changing the version to HTTP 1.1?
