- I'm not sure how the license file could be corrupted. Licenses dependent on alterad can be checked out, but those dependent on mgcld cannot.
- I'm not sure what is meant by your second bullet point. Are you referring to the path in the license file? Which instance of mgcld should the license file be configured for? The debug.log is capturing log data, so I'm not sure that its location is relevant.
Attached is a screenshot of the firewall port settings. All 3 ports specified in the license file are open to the internal network.
