I am working with Azure DevOps Services on Self Hosted Agents.
Recently The Agent Stopped Working after more than 4 months.
Everything was looking ok when checking the Agents Page. All Pipeline were Queued, but no Agent was busy all was idle After Checking and rebooting agent i checked version of downloaded agent
And Then Updated to new agent version manually - and problem was solved.
Thanks
