OkHttp Android stream was reset: HTTP_1_1_REQUIRED – Twitter API

We are developing an Android application that should use Http/2 to connect to our Azure App Service.
On the Azure App Service we have Http/2 enabled by using the steps in the following blog post: https://blogs.msdn.microsoft.com/appserviceteam/2018/04/13/announcing-http2-support-in-azure-app-service/

Our requests are secured with Mutual SSL, so that the application has to send it’s client certificate.

When we try to execute a call to our app service with OkHttp, we always get the following error and stacktrace. When we try to do a call to the twitter api with the same Android code, this is working.

Does anybody have an idea on how to fix this?

We are using OkHttp version 3.10.0.

    HTTP/2 does not really support client certificates at this time – especially when such connections only apply to some of the resources on the server. There is a proposal to allow this, but it is not yet standardised and, AFAIK, not yet supported by any implementation.

    Until this is supported, the correct response is to suggest a downgrade to HTTP/1.1 with a HTTP_1_1_REQUIRED error code and the client should retry with HTTP/1.1.

    Other implementations do this as well as Azure.

    add this line in builder

    .protocols(Util.immutableList(Protocol.HTTP_1_1))

    like this

     private OkHttpClient client = new OkHttpClient.Builder()
            .protocols(Util.immutableList(Protocol.HTTP_1_1))
            .build();
