I have migrated several projects to our new server, and one gives me errors on all application queries (500).  Model queries work fine.. So I see the GUI, but never content. And the Indicium error log gives me always the error below.. There is no other logging.

Are you sure the database connection is correct and reachable. 

Hello Freddy,

I think your license in IAM may be empty:

select license
from global_settings

You should see messages regarding this in Indicium's error log. It should state that it attempted to retrieve a license but failed. Can you check this?

It has a license..  however the mentioned database and server don't match up anymore. (I've divided the old IAM into 2 new ones (PoC and Demo) ..  can this be the issue then?

I think I understand what happened. 

As this is a copy of the old IAM, I renamed the database. I thought I restarted the Indicium tier already, but apparently not. I just did another restart, and I saw the database corresponds again and the errors are gone. 

 

Hello Freddy,

That does indeed make the license invalid, however, I don't quite understand why you are getting the error that you are getting. And if the license is invalid, it should also attempt to retrieve a new license (which should show in the error log).

You could update your license in IAM to NULL and then restart Indicium to force the retrieval of a new license. You might have to register the environment in TCP again, however.

I will look into why this error occurs.

Oh good, that explains a few things. In that case you can disregard my last message.
