Getting this issue while execution of the pipeline, this pipeline is running on a windows agent connected using JNLP Protocol requesting help… Jenkins Version : Jenkins 2.356

I have tried Restarting jenkins but this still persists

Answer 1

it depends on where and how you run this agent

could be

• used non existing container on agent
• error during agent creation (infrastructure issue)
• wrong agent configuration
• different versions of java on agent and jenkins

i'd start from checking logs

also you can check logs in jenkins "manage->system log" https://www.jenkins.io/doc/book/system-administration/viewing-logs/#logs-in-jenkins

there you can add custom loggers (depends on how you run this agent)
