:; When running below command to configure an agent with the pmm server, i get timeout.
[root@pxc01 ~]# pmm-admin config --force --server-insecure-tls --server-url=https://admin:admin@172.17.0.2:443
Checking local pmm-agent status…
pmm-agent is running.

Failed to register pmm-agent on PMM Server: Post “https://172.17.0.2:443/v1/management/Node/Register”: dial tcp 172.17.0.2:443: i/o timeout.

Any pointers would be most appreciated.

Hi Manni,

Could you specify your client IP in the config command?

e.g.
pmm-admin config --force --server-insecure-tls --server-url=https://admin:admin@172.17.0.2:443 172.17.0.x generic pxc01

Hello Adivinho

Thank you for the reply.
pxc01 the ip is 172.42.42.101

So are you suggesting to use
pmm-admin config --force --server-insecure-tls --server-url=https://admin:admin@172.17.0.2:443 --client-address 172.42.42.101

Sorry I am a bit confused.

Usually Docker uses the default 172.17.0.0/16 subnet for container networking.
You may check your docker subnet by performing next commands

docker network ls
docker network inspect -f ‘{{range .IPAM.Config}}{{.Subnet}}{{end}}’ NETWORK

If it has the default value then your PXC node (172.42.42.101) is out of a network range.
Also please notice that it’s a real IP address. The private network 172.x.x.x has the largest CIDR block 172.16.0.0/12
