[SOLVED] Rancher-agent 401 error

Rancher 1.x
1

Hi,
Today I setup my ubuntu 14.04 server with docker.
Everything works with docker and cli utilities, downloading images etc.

Now I try to add this host to rancher and I also was successful.

But when I add an application from the catalog I see that the rancher-agent is starting with a 401 client error.
I see this in the rancher-agent logs:

2016-02-23 21:36:00,533 ERROR agent [140125455440144] [event.py:112] Error in request : 285dd989-1c13-45f7-96c7-60e11777a776

APIError: 401 Client Error: Unauthorized ("Authentication is required: Get https://registry-1.docker.io/v2/rancher/agent-instance/manifests/v0.8.0: unauthorized: incorrect username or password")

So what could be the problem here?
I constantly see in the rancher ui those starting rancher-agents with the 401 client error.

You are using the same host for the server and agent?

Have you made sure the IP of the host in the Rancher server (UI) is the correct IP?

Hi denise,
I solved the problem when I recreated the Environment again.
I don’t know what was wrong with the env, but now it is working properly again.

What I did once was to change the rancher hostname from hostname to FQDN in the settings.

Thanks for the hint denise.
