I use Eclipse Paho Android Service 1.1.0. When i try to use any Paho version above 1.1.0 (e.g. 1.2.0), AWSIotMqttManager is going to Reconnect after connect attempt throwing the exception:
MqttException (0) - java.io.IOException: WebSocket Response header: Incorrect upgrade.

Any advice how it can be resolved?

Hello @beersheba
Sorry to hear that you are running into issues. I tried to reproduce this behavior by using the AndroidPubSub sample (https://github.com/awslabs/aws-sdk-android-samples/tree/master/AndroidPubSub) with multiple versions of paho, (1.1.0, 1.1.1, and 1.2.0) and was able to connect and have pub/sub working.

Can you share more details about your setup and, if possible, a code-snippet to help debug this further?

In my setup i use both aws sdk and paho mqtt.
As i see in aws iot source, it's also using paho mqtt 1.1.0 internally.

    implementation 'com.amazonaws:aws-android-sdk-core:2.6.15'
    implementation 'com.amazonaws:aws-android-sdk-iot:2.6.15'
    implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.1.0'
    implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'

When i increase paho client version to 1.2.0 in app gradle, AWSIotMqttManager starting to throw the exception.

@beersheba Do you face this error when you use 1.1.0? Or does this error occur the moment you upgrade your app from 1.1.0 to 1.2.0?

[beersheba]

@kvasukib no, when i use 1.1.0 it works fine. Occurs on update

[mutablealligator]

It appears to be an issue with 1.2.0 version of the paho client. I am testing to see the compatibility of IoT SDK with 1.2.0 version of the paho client. Will post an update here shortly.

Is there a resolution identified for this issue?
I also noticed this while using 1.2.0, and it worked when I switched down to 1.1.0.
Thanks.

@cidoni
Unfortunately, We do not have a resolution yet other than using paho version 1.1.0.
This is an ongoing paho issue and is being tracked here. Please feel free to upvote the issue there so that it can gain traction.

Hello @desokroshan,

We are still facing this issue with Google Pixel 3 device with the latest version 2.44.0. Any resolution for this issue?
