iam/Appid is not bound? 404 or 500

Hi, 

got something I don't understand. 

When i open <url>/FF-OSL-Universal-lab-API/api/

I get; 

When I go to;

<url>/FF-OSL-Universal-lab-API/api/iam/iam

I get (a login screen, and when logged in);

When I check in IAM I have an active App; 

However, When i call; 

<url>/FF-OSL-Universal-lab-API/api/iam/344
i get
→ redirect to http:// (not https) and a 500 error

→ If I force https:// i get a timeout error. 

Also, trying the alias is not working; FF-OSL-Universal-lab-API/api/iam/ff → same issue. 

When opening; <url>FF-OSL-Universal-lab-API/api/iam/iam/gui_appl
gives me: 
 

So, the id is found  (the active app is is further down the line..) 

BUT : 

Notice the the URI is suddenly changed.

I open:

<url>.com/FF-OSL-Universal-lab-API/api/iam/iam/gui_appl

and get;

<url>.com/iam/iam/$metadata#gui_appl

Where did my Indicium Universal part of the uri go?!

Anyway, any thoughts on this are more than welcome! Been puzzling for quite some hours now. 

Kind regards, 
Alex
