Hi everybody,
i’am new to checkmk and trying to configure the agent but getting the same message, i couldn’t understand why.
Basically i installed checkmk site into Docker then i installed the agent into the desired server, but when i run the command:
sudo cmk-agent-ctl register -vv --hostname name --server ip:8000 --site cmk --user user --password pass

i’am getting the desired certificate but after i got:

Do you want to establish this connection? [Y/n]
> y
DEBUG [reqwest::connect] starting new connection: https://ip:8000/
DEBUG [reqwest::async_impl::client] response '401 Unauthorized' for https://ip:8000/cmk/agent-receiver/pairing
ERROR [cmk_agent_ctl] Error pairing with ip:8000/cmk

Caused by:
    Request failed with code 401 Unauthorized: You need to be authenticated to use the REST API.

If somone could explain to me, what’s wrong or help me with the right documentation.

What do mean by automation user ?
You mean using ansible to install it ?

[…] Checkmk provides the concept of automation users. These users are exclusively for remote control and do not allow a normal login via the GUI. […]

Glad it helped, but you should probably mark @mey.eric’s reply as the solution, not mine.
