Mqtt Client Can't connect through http proxy #1024

Hello,

mqtt paho java client cannot connect to server through http proxy from an android device. Getting below error: ERROR-MqttAgent Error message: Connection to the Mqtt Failed due to MqttException (0) - java.net.SocketTimeoutException: after 90000ms: isConnected failed: ETIMEDOUT (Connection timed out)

Tried to check if same issue is there using android service, but when using android service got below error: java.lang.IllegalArgumentException: com.lenovo.udcsystem: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

Is there any way to send http proxy details to Mqtt while making a connect call to make a successful connection?

Any help is greatly appreciated. Thanks!

https://github.com/eclipse/paho.mqtt.java/pull/1010 The changes in this PR provides proxy support. I tried building code and tested it and it does establishes the connection to over a proxy. Is there any plan to merge this PR?
