"Failure to return license click check" in PostgreSQL with none of the usual causes
I've had to switch from the Neo4J ThingWorx to using the PostgreSQL version of ThingWorx. I de-installed the current version, deleted ThingWorxStorage and ThingWorxStoragebackup and installed the PostgreSQL version.
When I started ThingWorx again I got the message "Failure to return license click check".
I read this document, and I
- Have plenty of disk space
- Have plenty of memory
- Have no Neo4J storage
- Have deleted all previous storage
What might be causing this problem?
