Pmm-client registered to pmm-server but metrics not visible

,
1

Hello everyone,

I have successfully registered pmm-client to pmm-server and even the status shows ‘registered’
But the metrics are not visible on pmm-server.

I have used this command to register:

pmm-admin config --server-url=https://<user>:<password>@<server IP>

Checking local pmm-agent status...
pmm-agent is running.
Registering pmm-agent on PMM Server...
Registered.
Configuration file /usr/local/percona/pmm2/config/pmm-agent.yaml updated.
Reloading pmm-agent configuration...
Configuration reloaded.
Checking local pmm-agent status...
pmm-agent is running.

After this if i run the following I am getting this:
 $ pmm-admin summary
Failed to get PMM Server parameters from local pmm-agent: pmm-agent is not connected to PMM Server.
$ pmm-admin status
Failed to get PMM Agent status from local pmm-agent: pmm-agent is not connected to PMM Server.

But the metrics for this client is not visible, anyone please help me with this.
thanks

I thought it was a sync issue, but it is not and the status is still unknown
Attaching my /var/log/syslog

As the status on CLI says registered and connected , when i try to explicitly unregister the node, i get the following error:

# pmm-admin unregister --force 
Failed to get PMM Server parameters from local pmm-agent: pmm-agent is not connected to PMM Server.

It is very confusing, where is all my pmm-clients metrics been pushed to? PMM server dashboard is still the same the status of this node is still UNKNOWN.

I’ve searched everything possible, still the same, if the CLI shows that the pmm-agent is running I am unable to find where the traffic is going from pmm-client, any hint on what could’ve gone wrong , is it a network issue ?
If someone pointed me the right direction that could be a great help !
Thanks
