Hello everyone, I had actually uninstalled pmm-client package and re-installed it again using package manager(debian), I am using ubuntu 20.0.4 , I have successfully installed the pmm-client , but I am unable to register it with the server. The pmm-server is up and running and the dashboard is also accessible. this is the command i used to register the pmm-client to pmm-server _pmm-admin config --server-insecure-tls --server-url=[https://admin:admin@10.57.58.215:443](https://admin:admin@10.57.58.215:443) 10.57.58.72 generic stg-sanjana102_ My ip-addresses are correct and they are pingable too. the error I am facing is, Checking local pmm-agent status… pmm-agent is running. Registering pmm-agent on PMM Server… Failed to register pmm-agent on PMM Server: Post “[https://10.57.58.215:443/v1/management/Node/Register](https://10.57.58.215:443/v1/management/Node/Register)”: Service Unavailable. Please help me with this. Thanks ---

Does this work? ``` curl -k https://10.57.58.215:443/swagger/ ``` If this returns failure, then you have some sort of firewall issue or your pmm server container was not configured correctly to map ports. ---

Issue is resolved, it was a very strange problem, actually when i was trying to register the node i was logged in as root user (sudo su) , I simply exited from sudo su and tried to register the pmm-agent using _sudo pmm-admin config --server-insecure-tls --server-url=[https://admin:admin@10.57.58.215:443](https://admin:admin@10.57.58.215:443) 10.57.58.72 generic stg-sanjana102_ It worked this time. I still don’t know why this problem exists, i have also unregistered the agent and again logged into root and tried to register again which again failed, but when i exit sudo su it works. ---
