Hi Chinna,

Is this by any chance linked to the following?

> [@Failed to establish two-way communication channel: context canceled. component=client](https://forums.percona.com/t/failed-to-establish-two-way-communication-channel-context-canceled-component-client/19566/):

> PMM works fine for a period like 2 weeks or 1 months, but facing “failed to established two way communication” issue on some of the agents. we are not using any proxy behind the connectivity for server to agent connection. some times restarting pmm-server helps to reconnect agent, but pmm2-admin list command not showing any output, simply stalled. Then again it went to the same issue. we have a oneway port opening from client to server.
