I'm getting the following when trying to run coe commands from my laptop:
Request to https://openstack.eqiad1.wikimediacloud.org:29511/v1/clusters timed out

which seems reasonable, as that endpoint doesn't seem to exist on openstack with the /clusters suffix.

I've installed the python3-magnumclient (I'm running ubuntu 22.04.1) which appears to get me much the same version as exists on cloudcontrol1005. Mine:

ii  python3-magnumclient                  3.5.0-0ubuntu3            all          client library for Magnum API - Python 3.x

cloudcontrol1005:

ii  python3-magnumclient                  3.5.0-3~bpo11+1           all          client library for Magnum API - Python 3.x

coe commands do seem to work fine from cloudcontrol1005 itself.

I'm guessing this is either my client is trying the wrong endpoint (seems to work with other things like openstack server list) or something isn't being allowed from external sources?
