I've got Unimus 2.2.2 and am trying to sync with Observium 22.3.11904

I've created the connection:
* Server url is http://our-observium-server
* credentials are verified - have tried using readonly and admin creds
* sync rule is configured as default zone

When I try 'run sync now' I get the error:

Import error:
HTTP response code is not 2xx. Code 501.

if I go onto the server's cli and do 'curl https://our-observium-server' then I can see the HTML for the login page as I'd expect.

"curl -s -o /dev/null -w "%{http_code} http://our-observium-server" returns 200 as well.

For anyone finding this topic in the future, the issue in this case was that the Observium API was turned off in Observium settings.

To NMS Sync with Observium to work, 2 requirements need to be met:
- paid (subscription) version of Observium (free version does not have the API)
- enable the API feature in Observium global settings

We have also added this to our Wiki article on Obserium NMS Sync:
