Unable to register pmm-agent on pmm server

1

Hi team, i have installed pmm3-server and pmm3-client on 2 machines.

I am reciving following error while registering pmm-agent on pmm server using command:

pmm-admin config --server-insecure-tls --server-url=https://admin:admin@X.X.X.X:443

Error: Failed to register pmm-agent on PMM Server: Endpoint not found: /v1/management/Node/Register, http method: POST.

Can anyone plz help on this..

Hi, can you confirm the versions of both PMM server and client (with pmm-admin it’s pmm-admin --version).

Also, you can run pmm-admin with debug flag for more information:

pmm-admin config --server-insecure-tls --server-url=https://admin:admin@X.X.X.X:443 --debug
