Jenkins Windows Slave JNLP Connection Error

I am trying to setup jenkins slave on windows vm and keep it as a service. I did the following steps

went to jenkins master from my slave and downloaded the jnlp slave agent and installed it. Connected to jenkins logs in master. and a small window to show that I am connected came up with it too.

JNLP agent associated with /10.xx8 <=== [JENKINS REMOTING CAPACITY] ===> Slave.jar version: 2.51 This Windows Slave is successfully connected and online

After that, I installed it as a service with jenkins user that I am using. When I close a small connected window on my slave, the following error appears

Then I added proxy settings to my jenkins-slave.xml but still get the same error. My jenkins-slave.xml arguments are as follows

<executable>C:\Program Files\Java\jre7\bin\java.exe</executable>
  <arguments>-Xrs -Dhttp.proxyHost=xx.xx.xx -

Dhttp.proxyPort=3128 -jar "%BASE%\slave.jar" -jnlpUrl https://example.org/computer/Windows%20Slave/slave-
