Hey all,  
I have installed the recent LTS version of Jenkins in windows, I have connected two windows agent machines which has same configuration as my controller machine and same version of Java.

Now, my problem is agents are getting disconnected for every 7hours, even though jobs are running in it and getting connected back in few seconds.

I have connected the slaves through the batch command given in the agent page of Jenkins.

I doubt this is a Jenkins problem. More likely related to your network that something is terminating the websocket after 7 hours.  
PS: the term `slave` is deprecated please use `agent` instead

Thanks Markus!  
I had tried with two versions of Jenkins, still disconnecting periodically.

1. Is there any other way to connect to agent instead of websocket.?
2. how to remove the timeout of 7hrs in network settings?
3. or any other method is there to connect Jenkins, I had tried already with the windows service and running the command through cmd, still issue persists.

1. you can try with ssh (the connection is initiated from the Jenkins controller) but it requires that you have the openssh properly configured on the agent machines. But there is no guarantee that you don’t run into the same problem with the timeout
2. I don’t know where this timeout could be coming from but it is not Jenkins. Ask the responsibles for your network in your IT department

do you have some reverse proxy setup by chance?

No, I do not have any reverse proxy

```auto
netsh winhttp show proxy

Current WinHTTP proxy settings:

    Direct access (no proxy server).

```

I am facing this issue after migrating my Jenkins to other windows machine.

Issue solved after connecting the agent without websocket option in the command!
