I'm getting this error message whenever I try to access the GeoEvent 10.6 manager site:
Even though, ArcGIS Server seems to be correctly licensed:
I've re-loaded the ECP file, edited de Keycodes file, restarted services and even the server itself without any Success.
My OS is Ubuntu Server 16.04
Thanks ins advance for your help.
I recently had this issue myself on a Red Hat VM which was abruptly turned off. In my case, I think some level of corruption occurred and I had to blow everything away and re-deploy on a new VM. Assuming your situation is like Sergio's and everything checks out with your licensing/keycodes file and there is no other obvious answer, I would start with checking folder permissions. You'll want to ensure that the account running GeoEvent/ArcGIS Server has appropriate permissions on content/application directories. Assuming you're on Linux, that means recursive 770 permissions. It's also a good idea to have that account be the owner of directories.
If all that looks good and still you get that error, then you can try the below (ideally you have a backup of your configuration):
