I have a workflow on knime server (4.5 on linux) which contains linked meta nodes. When I select the workflow in the web frontend I get an Load Error with http response code 403. The URL to the meta node displayed in the error message is correct. If I use the URL I can retrieve the meta node manually from my local machine (since I am authenticated I guess), but the server seems not to be authenticated against the rest endpoint.
Is there any specific configuration which has to be set, so that the server can retrieve linked meta nodes? I have the server and executor on the same machine, but I had to set "com.knime.server.canonical-address" in the knime-server.config since the server URL was resolved incorrectly before.
