[RLM] Communications error with license server (­17)

These warnings mean that Arnold can connect to the RLM license server, but Arnold cannot connect to the solidangle ISV server:

00:00:12 14MB WARNING | [rlm] * Communications error with license server (­17)
00:00:12 14MB WARNING | [rlm] * Connection refused at server (­111)

Usually the problem is that the solidangle ISV server is not running.

You can check the status of the solidangle ISV server with RLM Web Admin. I like the get the RLM diagnostics (Diagnostics > Run Diagnostics) from RLM Web Admin and review that.

In rare cases, the problem is something else, such as:

  • Some sort of network connection problem. For example, I recently had a case where we would get these warnings when we used the IP address of the license server in solidangle_LICENSE. But as soon as we switched to using the hostname, everything worked.
  • Another RLM instance is running and listening to port 5053, and that instance doesn’t have a solidangle ISV running. I heard about this second-hand, from a customer; I didn’t see it with my own eyes and I don’t know how it’s possible. You can have multiple RLM instances running, but each instance has to have a different port otherwise you get ” “Port 5053 in use, waiting…” messages and the second RLM won’t start.
