Could not start a Port Forwarder on the local machine for port 30306

Same issue as here: Licensing Error: LICENSE_CHECKOUT_BUCKET_SIZE environment variable is not set

The post indicates the BUCKET_SIZE error is fine, so focusing on fact that an address is already in use.
AWS render with maya limit works fine.
AWS render with maya with vray limit errors:

2024-05-08 03:31:16:  Could not start a Port Forwarder on the local machine for port 30306. This is likely due to a port conflict. Please ensure that you are not running a License Forwarder or another Worker on this machine and that no other process are attempting to bind to this port.

30306 not in use according to netstat.
we do have a vray license server running in one of the domains but not on this (new)server.

What do I look at next?
Best

Since the log line is repeated several times - are multiple processes trying to start on the same port?
