Not able to view Models on ARIS Architect drawing board

Hello,

judging by the logo of your ARIS Architect client, it seems to be a rather old 9.x release. Is it possible, that it is locally installed and does not match the version of the server you are connecting to? To be sure you have a matching version for the server use the download client from the server:

You get it from https://my.aris.server/#tenantname/downloadclients

Replace the tenantname and host address with the coordinates of your installation. You may have to login first.
