com.jetbrains.bundle.exceptions.BadConfigurationException: The property http.proxyHost is unknown and could not be set by configure command
Attempt to configure license server by
<license_server_home>\bin\license-server.bat configure --<property> <value> for Windows leads to "The property <property> is unknown and could not be set by configure command" and causes no change of configuration data.
If this doesn't help try to upgrade to recent version of License Server available at the download page.
