yes full and legal licenses i have from render legion.
i added now a 4th node now to test, this also refuses to work. so from 4 nodes 2 cant render:/
corona lic server runs of course as it runs local and on 2 of the 4 nodes,
all 4 have internet connection and connection to the main machine where the lic server runs.
lic server runs before i installed and started the nodes. i installed all 4 today, all in same way, 2 refuse to work, the others are ok.
some seems wrong yet sadly in TR....
the same nodes runs fine in other renderers or c4d internal. so it seems some corona specific.
