I am trying to connect to an AWS MQTT broker/server using the Hive MQ client library for Android Studio (v1.3.0) with an AWS pre-signed URL.
implementation("com.hivemq:hivemq-mqtt-client:1.3.0")
implementation(platform("com.hivemq:hivemq-mqtt-client-websocket:1.3.0"))
The parameters I am using are shown below with the sensitive information removed:
host: xxx.amazonaws.com
path: /mqtt?X-Amz-Algorithm=xxx&X-Amz-Credential=xxx&X-Amz-Date=xxx&X-Amz-SignedHeaders=host&X-Amz-Signature=xxx
This is my latest attempt to connect:
MqttClient.builder()
.identifier(UUID.randomUUID().toString())
.serverHost(host)
.webSocketConfig()
.serverPath(path)
.applyWebSocketConfig()
.sslWithDefaultConfig()
.useMqttVersion3()
.build()
But when connecting, I get the error:
com.hivemq.client.mqtt.exceptions.ConnectionFailedException:
io.netty.handler.codec.http.websocketx.WebSocketHandshakeException:
Invalid handshake response getStatus: 426 Upgrade Required

I'm getting this error when trying to connect to the server I opened locally.
It converts ws to http. and put a # sign at the end.
Socket:
final channel = IOWebSocketChannel.connect(Uri.parse('ws://192.168.1.226:10600'));
**Error: **
Restarted application in 1.052ms.

The server was created with .net 4.8.
I would be glad if you help
I want to show the messages sent by the server in the application.
I'm using volley in my app and send request to my server but i got this error from my onErrorResponse volley:
Error: com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: Read error: ssl=0xb4000071bca8e448: Failure in SSL library, usually a protocol error

I'm using device with android 11 and the request does not work what should i do?
Make sure you have connected to wifi
PostGraphile v4.9.2 server listening on port 5001
‣ GraphQL API: http://0.0.0.0:5001/graphql
how can i change http to https. i mean, i want https://0.0.0.0:5001/graphql
because, i am getting error while debugging my ionic capacitor app for android
E/Capacitor/Console: File: http://localhost/vendor-es2018.js - Line 41539 -
Msg: ERROR Error: Http failure response for http:// mydomain .com:5001/graphql: 0 Unknown Error
i think it is about http problem but as you see it is unknown error. Thanks in advance
i found the solution here: How to allow all Network connection types HTTP and HTTPS in Android (9) Pie?
i allowed http requests in manifest.xml and i added networkSecurityConfig.xml
Thank you all
I am connecting to a server which has TLS support with SSL certs. I am getting a SSL Handshake error on Android app client. I also use useTransportSecurity() to deal with TLS negotiation type. Is there any workaround to get away with this error without certificate pinning?
Error encountered:
Caused by: java.lang.RuntimeException: protocol negotiation failed
at io.grpc.okhttp.OkHttpProtocolNegotiator.negotiate(OkHttpProtocolNegotiator.java:96)

at java.lang.Thread.run(Thread.java:764)
And this is how I generate my channel :
ManagedChannel mChannel = OkHttpChannelBuilder.forAddress(host, port)
.useTransportSecurity()
.build();
Appreciate your time and help.
ALPN is failing during the TLS handshake, which prevents gRPC from negotiating HTTP/2. Either you aren't connecting to a gRPC / HTTP/2 server or your client's TLS library is too old.
Please review the SECURITY.md documentation. Namely, you probably want to "install" the Play Services Dynamic Security Provider into the runtime when your app starts.
it might be rather a matter how you create the server; see SECURITY.md for Mutual TLS ...
Server server = NettyServerBuilder.forPort(8443)
.sslContext(GrpcSslContexts.forServer(certChainFile, privateKeyFile)
.trustManager(clientCAsFile)
.clientAuth(ClientAuth.REQUIRE)
.build());
Answering my own question.
This error comes from the ALPN TLS extension, which I needed my SSL endpoint to support. I was using NPN, and that is why I was unable to connect.

trying to connect ROS v1.8.3 with android realm 4.1.0, but got an error on connection:

is it version incompatibility issue?
previously it works well with realm 3.4.0 build. only changes i've made during migration:
project gradle:
classpath "io.realm:realm-gradle-plugin:4.1.0"
gradle:
android {
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.2'
}
code (added <SyncUser>):
SyncUser.loginAsync(syncCred, serverH, new SyncUser.Callback <SyncUser> () {...
application have been deleted from phone before install with new realm build.
is some other options required?
logs on server:
sync: HTTP Connection[2165]: Connection is closed after HTTP response.

sync: HTTP Connection[2165]: HTTP request received, url

Realm 4.0.0 was updated to use Realm Sync 2.0.x, which requires ROS 2.0 which is most likely incompatible with ROS 1.x.
The last version to use Realm Sync 1.x is 3.7.2.
