Property http.port unknown

[steamfan]

Hello,

since today I encounter a problem with one of my MinimServer installations:

• MinimWatch states (red icon) that the integrity check failed
• within the startc command line program the http.port is not set
• setting it with 'prop http.port=9800' gives an error message 'Unknown component name'
  

'about' gives
