pmm-admin config - does not look like a pmm server

hi guys,
i have a postgresql server called ServerB
i installed pmm in docker in another instance called ServerA. 
both servers are ubuntu.

I am stuck here. I can confirm i can telnet the port and connectivity is fine. This is on Google cloud instances.

root@ServerB:~# pmm-admin config --server-insecure-ssl --server ServerA:443 --bind-address ServerB --client-address ServerB --server-password admin --server-user adminUnable to connect to PMM server by address: ServerA:443
Even though the server is reachable it does not look to be PMM server.Check if the configured address is correct. Unexpected response code: 404 (Not Found)
any ideas what can i do to get things kicking?

thanks.

If you go to ServerA from ServerB do you See PMM Login Screen ?
This message means is whatever listening on port 443 on ServerA is not PMM Server  - might be this port was busy when you spinned up docker container ? 

Are you using the same PMM 2.x version? pmm-admin does not provide --bind-address flag in 2.x.

you are correct here. The pmm percona server is on pmm2 and the client is pmm1. but i installed it with the percona repo

i made the mistake of installing pmm-client instead of pmm2-client. now it works. thanks!
