trying to connect ROS v1.8.3 with android realm 4.1.0, but got an error on connection:
Connection[1]: Writing failed: End of input

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]: 404 Not Found
sync: HTTP Connection[2165]: HTTP request received, url
sync: HTTP Connection[2165]: Connection initiates HTTP receipt

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.

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:

‣ 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

Trust Anchor not found for Android SSL Connection

EDIT
It does not seem to be a duplicate to me since all the other questions are related with repeatable issues and not intermittent like this one
END-EDIT
I have an app that runs some HTTP GET.
The app runs on API 21+.
It works fine most of the time, but very rarely one HTTP GET fails with the error:
D/OkHttp: --> GET https://url/url2?parm1=value1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
When this starts happening, it keeps happening until I kill the app.
I'm using Retrofit with OKHttp 4.3.1. I'm going to update to the latest version now just in case this is a bug in OKHttp but I didn't find any report.
The code for the HTTP call is the usual code with Retrofit:
private val retrofit: Retrofit
get() = Retrofit.Builder()
.baseUrl(BuildConfig.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.addCallAdapterFactory(CoroutineCallAdapterFactory())
.client(client)
.build()
internal val service: AppService
get() = retrofit.create<AppService>(AppService::class.java)
internal interface AppService {
#GET
suspend fun loadServerListAsync(#Url url: String): Response<List<Server>>
}
In the past I have seen this error in another app. In that case the error wasn't intermittent and the problem was on the backend: they had changed a certificate, but they hadn't updated all the intermediate certificates.
In this case it looks like the error is different since it is intermittent and killing the app fixes it. There is no load balancer on the backend so it can't be that different servers have different certificates.
It can be related from cypher security protocol TLSv1 to fail and fallback to deprecated SSLv3.
To prevent TLSv1 secure connection to fallback to SSLv3 in simulator and throw connection error because SSLv3 is now deprecated and unsecure (Android Studio Failure in SSL library, usually a protocol error)
Install updated security provider using Google Play Services.
This effectively gives your app access to a newer version of OpenSSL and Java Security Provider, which includes support for TLSv1.2 in SSLEngine.
Once the new provider is installed, you can create an SSLEngine which supports SSLv3, TLSv1, TLSv1.1 and TLSv1.2 the usual way.
This should be the answer to your problem : Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: Failure in SSL library, usually a protocol error

How to solve this problem?
